Product Specification ::

BROILTECH Thermal mass flow meter for detection and metering the gas and air. Its work on principal of calorie amount taken away from the heated sensor by a fluid flow is calibrated to the mass of flow,

 

Thermal mass flow meter use for measuring : air, nitrogen, argon, co2, chlorine, ethane, ethylene, methane, ammonia, helium, hydrogen, bio gas,

 ,

2) DISPLAY

Power voltage: 85 v ac – 250 v ac OR 24V DC 10%

display mode:

Liquid Crystal Display (LCD), as follows:

     L XXX. X    four instantaneous flow (m3 / h) or L/h

    XX. XXXXXX eight cumulative flow (m3)  or L

temperature reading

Cumulative flow: automatically expand the display precision, the cumulative flow values can be reset.

Power-fail protection: instrument coefficient, the Total flow values ten years is not lost when power supply drop.
