HQF Mass Flow Meter
Mass flow meter developed by HOLYKELL is a Coriolis mass flow meter. Based on the thermal principle, it can directly output mass flow. Therefore, it is suitable for most liquid and gas flow measurement.
Application :
●Domestic sewage discharge
●Factory wastewater control
●Air, oxygen and other flammable gases
●Thermal power station
Advantages
01Various types of pipelines are installed, and the scope of application is wider.
02It is suitable for flow monitoring of various types of liquids or other flammable and explosive gases.
03Self-developed core processor, mass flow accuracy up to ±0.002.
04Factory-operated shop, minimum order of one piece, worldwide free shipping.
