HL-HUF320 G1 / 2" G3 / 4" G1" cheap ultrasonic heat meter factory direct
Features:
1. Low comprehensive cost: no mechanical impeller rotation, no mechanical wear, low cost of later use and maintenance, The service life is much longer than the mechanical heat meter;
2. Good measurement reliability: the small impurities passing through the front filter of the heat meter will not affect the accurate measurement of the ultrasonic heat meter;
3. Less measurement disputes: When the ultrasonic heat meter is used, it does not block, does not wear, and the measurement is accurate, which is conducive to the smooth progress of the heat metering work;
4. Convenient maintenance: Ultrasonic heat meters are basically maintenance-free products.
