1. Elite Features of Trumsens Brand Thermal Gas Mass Flow Meter:
● Measuring the mass flow or volume flow of gas Do not need to do temperature and pressure compensation in principle with accurate measurement and easy operation.
● Wide range: 0.5Nm/s～1000Nm/s for gas. The meter also can be used for gas leak detection
● Good vibration resistance and long service life. No moving parts and pressure sensor in transducer, no vibration influence on the measurement accuracy.
● Easy installation and maintenance. If the conditions on site are permissible, the meter can achieve a hot-tapped installation and maintenance. (Special order of custom-made)
● Digital design, high accuracy and stability
● Configuring with RS485 or HART interface to realize factory automation and integration
2: Introduction of Trumsense brand thermal gas mass flow meter:
Thermal gas mass flow meter is designed on the basis of thermal dispersion, and adopts method of constant differential
temperature to measuring gas flow. It has advantages of small size,easy installation, high reliability and high accuracy, etc.
The meter contains two platinum resistance temperature sensors. The thermal principle operates by monitoring the cooling effect of a gas stream as it passes over a heated sensor. Gas flowing through the sensing section passes over two sensors one of which is used conventionally as a temperature sensor, whilst the other is used as a heater. The temperature sensor monitors the actual process values whilst the heater is maintained at a constant differential temperature above this by varying the power consumed by the sensor. The greater the gas velocity, the greater the cooling effect and power required to maintain the differential temperature. The measured heater power is therefore a measure of the gas mass flow rate.

7: Installation example from other buyers for Trumsese brand thermal gas mass flow meter:
Thermal meters require a fully developed flow profle as a prerequisite for correct flow
measurement. For this reason, please note the following points when installing the device.
●Obsenve the recommended inlet and outlet requirements.
●Good engineering practice is necessary for the associated pipe work and installation.
●Ensure correct alignment and orientation of the sensor.
●Take measures to reduce or avoid condensation (e.g. install a condensation trap,thermal insulation, etc.).
●The maximum permitted ambient temperatures and the medium temperature range,must be observed.
●Install the transmitter in a shaded location or use a protective sun shield.
●For mechanical reasons, and in order to protect the pipe, it is advisable to support heavy sensors. No installation in where large vibration exists
●No exposure in the environment containing a lot of corrosive gas
●No sharing power supply with frequency converter, electric welding machine and other machines which can make power-line interference. If necessary, please add power conditioner for transmitter power supply.

The Density and Conversion Coefficient of Common Gas
●According to different gas on site, the calibration in lab translates the flow rate of actual gas on site into flow rate of air, and then begins to calibrate the flow rate at present.
●Therefore, when using the meter on site, the meter displays mass flow or volume flow of actual gas.
●When translating the flow rate of gas into flow rate of air, there is a conversion coefficient table of different gas.
