热式气体质量流量计 是利用热传导原理测流量的仪表。 DXRSC thermal gas mass flow meter is an instrument that measures flow using the principle of heat conduction. The instrument uses the constant temperature difference method to accurately measure the gas mass flow. It has the advantages of small size, high digitization, convenient installation and accurate measurement. Accurate measurement for most gases. And can measure strong corrosive gas.
The sensor part consists of two reference-grade platinum resistance temperature sensors. Using a bridge loop, one sensor measures the flow temperature and the other maintains a constant temperature difference above the temperature of the fluid, allowing flow measurement under high temperature and high pressure conditions.
Thermal gas mass flow meters have the following technical advantages:
真正的质量流量计，对气体流量测量无需温度和压力补偿，测量方便、准确。 Ø A true mass flow meter, which does not require temperature and pressure compensation for gas flow measurement. The measurement is convenient and accurate. The gas mass flow or standard volume flow can be obtained.
宽量程比，可测量流速高至100Nm/s底至0.5Nm/s的气体，可以用于气体检漏。 ØWide range ratio, can measure gas with flow rate up to 100Nm / s bottom to 0.5Nm / s, can be used for gas leak detection.
抗震性能好使用寿命长。 Ø Good seismic performance and long service life. The sensor has no moving parts and pressure sensing parts, and is not affected by vibration to the measurement accuracy.
安装维修简便。 Ø Easy installation and maintenance. Where site conditions permit, non-stop installation and maintenance can be achieved.
数字化设计。 Ø Digital design. Integrated digital circuit measurement, accurate measurement and convenient maintenance.
采用RS-485通讯，或HART通讯，可以实现工厂自动化、集成化。 Ø RS-485 communication or HART communication can be used to realize factory automation and integration.
