Oval Gear Flow Meter

Oval gear fuel flow meter is a positive displacement volumatric flow meter, available with RS485/Pulse/Current/Hart output and inbuild flowrate and totalize digital display,

positive displacement flow measurment has accuarate and precision teethed two oval shape gear, Gear rotate when flow pass on measuring chamber and Magnetic pickup sensor/ Hall sensor use for measuring rotation  of gear, and each rotation equal to fix value of fluid volume,
Digital Fuel Flow Meter available with :
--- Inline battery operated digital display
--- 4 to 20 mA output inline digital display
--- Panel mount digital display
--- Mechanical counter flow meter

1) Battery operated fuel flow meter :

Power voltage: 3.3 V10AH lithium batteries can be used more than 5 years in a row.

display mode:
Double row 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

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. 

2) Fuel flow meter Display with 4 to 20 mA Output

Power voltage: 24 V DC
Output signal: 4 TO 20 mA
optional        : RS-485
                   : HART protocol
