The brief introduction of heating type mass-flow gas meter of the pipelike:

The heating type mass-flow gas meter utilizes the heat-conduction principle to examine the instrument of the flowrate. This instrument adopts the thermostatical differentiation to measure the gas mass flow rate accurately, it is convenient to have high, installation of small, digitized intensity, measure the advantage such as being accurate. The part of the sensor is made up of two reference level platinum RTDs, adopt the cycle of bridge, a sensor measures the flowrate temperature, it is bad that another sensor maintains the constant temperature higher than the fluid temperature, can carry on flow measurement under high temperature and high-pressure condition.


The characteristic of the products:

Measure the requirements conventionally: DN10-DN80;
Gaseous mass flow rate or volume flow rate of the standard of the direct display;
Can be used in the leak hunting of gas;
Can realize and wait to press installation, it is convenient to maintain, it is simple and convenient to safeguard;
Digitization is designed, the whole digitalizing circuit is measured, measurement is accurate;
Adopt RS-485 communication, can realize factory automation, integrated
Wide range than,there are high to 100Nm/s on measurable quantity velocity of flow, from bottom to gas of 0.5Nm/s,
Ruggedized and of good performance to have long performance life, sensor adiaphorous part and sensory part of pressure, not shaken the impact on survey accuracy.
