Application of Mass Flowmeter in Industrial Welding Protection Gas

Application of Mass Flowmeter in Industrial Welding Protection Gas The volume of the fluid is a function of the fluid temperature and pressure, a dependent variable, and the mass of the fluid is an amount that does not vary with time, space temperature, and pressure. As mentioned earlier, flowmeters, such as orifice flowmeter, turbine flowmeter, vortex flowmeter, electromagnetic flowmeter, rotor flowmeter, ultrasonic flowmeter and elliptical gear flowmeter, are commonly used in flowmeters. Volume flow. The amount of fluid involved in activities such as scientific research, production process control, quality management, economic accounting and trade handover is generally quality. Using the flowmeter only to measure the volume flow of the fluid is often unable to meet the requirements of people, usually also need to try to get the mass flow of fluid. It is only possible to obtain the quality of the fluid indirectly by means of correction, conversion and compensation after measuring the parameters such as temperature, pressure, density and volume of the fluid. This measurement method, the intermediate links and more, the accuracy of mass flow measurement is difficult to be guaranteed and improved. With the development of modern science and technology, there have been some direct measurement of mass flow measurement methods and devices, thus promoting the flow measurement technology progress. In the modern industrial control, the stability and accuracy of the full realization of the need for accurate measurement of gas in the industrial welding of the protection of gas output is also a more careful control of the steps to ensure that does not pollute the environment, Good to complete the welding task, the mixture of carbon dioxide and argon can control precision.

The world's fastest battery-powered NDIR CO2 sensor

Gas Sensing Solutions (GSS) Ltd, the LED-based NDIR detector specialists, continues to push the boundaries for CO2 detectors with the launch of its new SprintIR6S. GSS' unique SmartIR™technology has enabled it to create a sensor that can take up to 20 readings per second, which is a world record for NDIR CO2 detectors, and has a six times faster response rate than the SprintIR CO2 sensor*.

Ralph Weir, GSS' CEO, explained, "We are the only company producing CO2 sensors using LEDs and photodiodes and, as we make the LEDs and photodiodes ourselves, we have been able to develop ultra-fast response times that no other NDIR sensor can match. Typical NDIR CO2 detectors take several seconds or even minutes to take a reading - because they use slow-reacting IR sources, which need time and energy to warm up, like MEMS hotplates, micro-bulbs or filament-based micro-lamp technologies. Our LEDs, by contrast, are Solid State emitters, and illuminate almost instantly. With the new SprintIR6S, we've also minimized the sample volume down to only 2ml, which enables us to achieve our fastest ever response rates*. This puts us in a unique position to open whole new application areas for CO2 monitors that could never be addressed by slow responding sensors based on traditional IR sources."

Applications for this new class of ultra fast CO2 sensors include health where they can capture rapidly changing CO2 concentrations in the breathing cycle to provide diagnostic information, which can be used in fitness testing, breath analysis/measurement, capnography, sports science and veterinary to name a few. In Industrial Health and Safety applications, such as factories where CO2 is used for modified atmospheres to delay packaged food from spoiling, they can provide ultra fast detection of rising CO2 levels. Even a doubling or tripling of normal CO2 levels can affect concentration and productivity with higher levels having increasingly deleterious effects on health right up to unconsciousness and death.

"A leak from a CO2 canister or similar can push CO2 levels up from the normal 400ppm to several thousand ppm in seconds," added Ralph Weir. "You cannot smell CO2 and it is colorless. Yet it can present serious health problems at raised concentrations so, the sooner an alarm is raised, the sooner people can take remedial action. For example, restaurants and pubs usually have CO2 cylinders in the basement for the drinks but basements typically have poor ventilation so an undetected CO2 leak could suddenly raise the CO2 level when someone was in the basement and render them unconscious - or dead. Our new sensors can give the earliest possible warning."

GSS' multi-patented SmartIR™ technology detects the presence of CO2 by detecting how much light is absorbed by CO2 molecules as light passes through the sample gases - called Non-Dispersive InfraRed (NDIR) absorption. CO2 absorbs between 4.2 and 4.4 microns so that its presence is easily detected, and the amount of light absorbed indicates how much CO2 is present. Typically, CO2 detectors use a miniature heater (such as MEMS devices like micro hotplates, microlamp/microbulb or filament heater) to generate a range of wavelengths that have to be filtered down to the wavelengths needed, which is wasteful and energy inefficient, especially as a lot of heat is produced. By contrast, GSS developed the world's first commercial, mid-range IR LEDs that are specifically tuned to emit just at 4.2 to 4.4 microns, making them highly energy efficient. As a result, GSS CO2 sensors are the only NDIR CO2 sensors that can be powered by batteries - a single lithium cell can power a SmartIR sensor for up to ten years.

At less than a cubic inch (23.8mm in diameter and 24mm tall), the SprintIR6S operates at between 3.25 and 5.5V, with a power consumption of only 35mW. The SprintIR6S is available in measurement ranges from 0%to 100%.

GSS will be revealing the new SprintIR6S detectors at the Sensor + Test show in Nuremberg, Germany from 30 May to 1 June 2017.

High Speed Carbon Dioxide Sensor NDIR CO2 Sensor SprintIR Summary SprintIR is a high speed (20 Hz) CO2 sensor, ideally suited for applications which require capture of rapidly changing CO2 concentrations including metabolic assessment and analytical instrumentation.

Fast, Accurate Carbon Dioxide Sensor The SprintIR carbon dioxide sensor is the fastest, most accurate CO2 sensor on the market. A breakthrough in NDIR technology, the SprintIR uses advanced solid state Indium Antimonide LED’s and detectors to offer a robust sensor with no moving parts, no heated filaments, and incredibly low power requirements. The sensor comes in four versions - from 0% to 100% - all capable of the same high-speed CO2 measurement. This makes the SprintIR especially useful in biological applications. • High speed sensing (20Hz) • Measurement ranges from 0 to 100% • 3.3V supply • Low power requirement 35mW • Flow through adaptor (Optional)

GUVA-S12SD UV Sensor

The GUVA-S12SD UV Sensor chip is suitable for detecting the UV radiation in sunlight. It can be used in any application where you want monitor for the amount of UV light and is simple to connect to any microcontroller. I recently noticed that some sellers had little modules for this sensor at a reasonable price so decided to purchase one

The module, with a typical UV detection wavelength of 200 – 370nm, outputs a calibrated analog voltage which varies with the UV light intensity so basically all you need to do is connect this to an ADC input and read in the value.

This value ties in with the UV index, this looks something like this

Connection

The connections are straightforward and described below, I used 3.3v from my Arduino. This was mainly for compatibility with other development boards but the module works with 5v.

1. GND: 0V (Ground) 2. VCC: 3.3V to 5.5V 3. OUT: 0V to 1V ( 0 to 10 UV Index)

Layout

As said its a simple layout but here you go

Code

Simple code example that reads the value at A0 and outputs the results via the serial monitor, if you use 5v rather than 3.3v then you will need to change the 3.3 in the following line

sensorVoltage = sensorValue/1024*3.3;

Source code

void setup() { Serial.begin(9600); } void loop() { float sensorVoltage; float sensorValue; sensorValue = analogRead(A0); sensorVoltage = sensorValue/1024*3.3; Serial.print("sensor reading = "); Serial.print(sensorValue); Serial.println(""); Serial.print("sensor voltage = "); Serial.print(sensorVoltage); Serial.println(" V"); delay(1000); }

Testing

Open the serial monitor and look at the readings

sensor reading = 46.00 sensor voltage = 0.15 V sensor reading = 46.00 sensor voltage = 0.15 V sensor reading = 46.00 sensor voltage = 0.15 V sensor reading = 46.00 sensor voltage = 0.15 V sensor reading = 46.00 sensor voltage = 0.15 V

If you look at the image earlier that corresponds to UV index of 0 which is a relief because I tested this indoors

CO2 Sensor Occupancy Detection

A group of researchers at the University of California in Berkley have designed an algorithm that can count the number of people in a room when only the CO2 level is known.

The study, titled “Sensing by Proxy: Occupancy Detection Based on Indoor CO2 Concentration” used SenseAir’s K-30 carbon dioxide sensor module for occupancy detection. The "Sensing by Proxy" model is more accurate than previously used machine learning models, and could be used to improve the efficiency of Demand-Controlled Ventilation systems (DCV) currently in use.

DCV works on the principle that you can save energy by heating, cooling or adding fresh air to a room only when it is needed. While heating and cooling can be controlled with a thermostat, the amount of fresh air that should be added to a room can be controlled by a carbon dioxide level transmitter. When CO2 levels go up, fresh air is added until the CO2 levels return to normal (typically 10% or less of the background CO2 levels).

While CO2 transmitters in a DCV system are good at monitoring CO2 levels, they do not tell you the number of occupants in a room. This is important because indoor air quality models specify the optimum fresh air exchange rate per person. If you don’t know how many people are in a room, all the system can do is pump in fresh air until the CO2 level drops.

This is where Sensing by Proxy comes in. Using the K-30 sensor’s CO2 level data as the only input, the researchers were able to create a model “that captures the spatial and temporal features of the system and links unobserved human emission to proxy measurements of CO2 concentrations.”

The algorithm they developed was tested in both controlled and field experiments, and resulted in an error rate of 0.6 fractional persons as compared to 1.2 fractional persons by the best alternative strategy. The algorithm is also better at measuring changes, such as occupants entering and leaving a meeting. In addition, it does not require more costly Pyroelectric infrared (PIR) or Ultrasonic sensors used for current occupancy detection systems.

The algorithm is one of a growing number of papers that test the use of CO2 levels for occupancy detection. For example, Chaoyang Jiang and others in a paper titled “Indoor occupancy estimation from carbon dioxide” were able to estimate occupancy in an office with 24 cubicles. They counted occupants accurately 94 percent of the time within a tolerance of four occupants.

While DCV is initially more expensive to install, improvements like this could be used to further reduce the long-term energy costs in DCV controlled buildings.

Product Specification

SO-E1-050 Limiting Current Type Sensor Oxygen Sensors

When voltage is applied to a zirconia electrolyte cell, oxygen is pumped through the zirconia disc from the cathode side to the anode side because the carriers of the current flowing through the zirconia electrolyte are oxygen ions. By attaching a cap with a pinhole on the cathode side of the cell and by increasing the voltage over the cell the current shows saturation due to the rate limiting step in the transfer of oxygen to the cathode. This saturation current is called limiting current and is nearly proportional to the ambient oxygen concentration.

Below the advantages of the oxygen sensor: measuring range 0.05 to 5 vol.% oxygen High accuracy For many types a more or less linear characteristic Small temperature dependence of the sensor signal Low interference with other gases Long service life In many cases “Single point calibration“ necessary only once

Applications: Medical Laboratory Food industry Household/Gastronomy Measuring technique Security technology/Monitoring (Electrical-) industry

Characteristic Data: Measuring gas: Oxygen concentration Measuring medium: Gaseous atmosphere Measuring principle: Limiting current type sensor Measuring ranges: 0.05 – 5.0 vol.% O2 Response time (t90): 2 to 25 sec. (Depends on: sensor type, gas flow, measuring chamber) Sensor voltage / heating voltage / power consumption / heater cold resistance Sensor voltage: 0.7 to 1.6 Volt Heating voltage: 3.6 – 4.4 Volts Power consumption: 1.3 to 1.8 Watts (depends on application and packaging) Cold resistance: R( 25°C ) = 3.25Ω ± 0.20Ω

Warm up time: Min. 30 s Maximum permissible operating temperature: 350°C (*) *Depending on the cable and filter assembly (see paragraph: specification, Cable assembly)

Permissible volumetric flow rate (Purging the sensor) For all sensor types, the maximum flow rate depends on the way of purging the sensor (sensor in direct gas flow, gas beam shape, etc.) and the size of the measuring chamber. Exception: SO-E1-xxx (TO8 + hose connection for direct gassing). Permissible flow [ml/min]: 100 - 500 (optimal: 250)

Lifetime (MTTF): ~ 20.000 hours (*) *Depending on measuring medium. Stated lifetime refers to a heated, operated sensor of type SO-xx-250 and SO-xx-960. A failure or reaching the lifetime typically means a slight deviation from the dispatch specifications.

Vibration resistance Sensors based on the TO8 socket as well as those built with a TO39 socket (SO-Bx-xxx, SO-Ex-xxx, SO-Ax-xxx) meet the European Norm EN60068-2-6 (Sinusoidal vibration tests).
