Overview
The thermal gas mass flowmeter is easy to install, easy to maintain, and has bi-directional detection. It is vibration resistant up to 8 points and can measure output analog quantities. It can calibrate multi-point nonlinear curves and has a wide range ratio of 100:1. It can simultaneously detect flow and temperature, switch to display large caliber small flow measurement, and can be used for leakage detection. It adopts proprietary technology "double balance structure" packaged sensor proprietary high humidity and high temperature algorithm. The medium temperature can reach 500 ℃ and can directly detect mass flow without temperature and pressure compensation.
Product Details
Thermal gas mass flowmeterworking principle:
Thermal flowmeter is a flow meter designed based on the principle of thermal diffusion When a fluid flows through a heating object, the amount of heat lost by the heating object is proportional to the flow rate of the fluid The sensors of this series of flow meters have two standard grade RTDs, one used as a heat source and the other used to measure fluid temperature. When the fluid flows, the temperature difference between the two is linearly related to the flow rate, and this relationship is then converted into a linear output of the measured flow signal through microelectronic control technology.
