HQF Mass Flow Meter

Product description

Download

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

01 Various types of pipelines are installed, and the scope of application is wider.
02 It is suitable for flow monitoring of various types of liquids or other flammable and explosive gases.
03 Self-developed core processor, mass flow accuracy up to ±0.002.
04 Factory-operated shop, minimum order of one piece, worldwide free shipping.
