 Application: 
 JH-HLUG series with temperature and pressure compensation-in-one flowmeter, the fluid medium is mainly used for industrial pipe flow measurements, such as gas, liquid, vapor and other media. Pressure loss is characterized by small, measuring range, high precision in the measurement conditions are not nearly the volume density of the fluid flow, pressure, temperature, viscosity and other parameters. No moving mechanical parts, so high reliability and little maintenance. Long-term stability of the instrument parameters. This instrument uses piezoelectric stress sensors, high reliability, can be -20 ℃ ~ +250 ℃ operating temperature range. With analog standard signal, but also digital pulse signal output, easily supporting the use of computers and other digital systems, is a more advanced, the ideal flow 
 Can be seen from the above equation, VSF output pulse frequency signal from fluid properties and composition changes, that instrument coefficient in a certain Reynolds number range, and only with the bluff body shape and size of the pipe and so on. But as the material balance and energy flow in the measurement of mass flow to be detected, then the flow meter should also monitor the volume of the output signal flow and fluid density, fluid properties and composition of the flow measurement or have a direct impact. 
 Karman vortex flowmeter vortex principle is the basis for Measurement of fluid flow in closed conduits new flow meter. Media because of its good ability to adapt, without direct measurement of temperature and pressure compensation can be steam, air, gas, water, liquid volume flow conditions, with temperature and pressure sensor measures the standard volume flow and mass flow conditions, is to cut expenditure flowmeter ideal alternative. 
 Vortex flow meter to improve the high temperature and vibration performance, my company recently developed a HLUG improved vortex flow sensors, because of its unique structure and selection so that the sensor may be at high temperature (350 ℃), high Zhendong (≤ 1g) use of harsh conditions.
