Fuel Meters Series VZO 15/50

Description of fuel meters:

Flow meters for liquid fuel with a mechanical roller counter. Designed for installation on industrial burners and boilers, as well as on locomotives and river vessels, on all types of engines with fuel consumption ranging from 10 to 30 000 l/h.
The fuel meters have threaded connections (index RC) with the diameter DN 15, 20, 25, 40 mm or flange connections (index FL) with the diameter DN 15, 20, 25, 40, 50 mm.

Main specifications:
– temperature of the measured fuel up to +180°С;
– nominal pressure in the fuel system up to 16 bar;
– error range: ±0,5% from the actual value, repeatability ± 0,2%. Protection class IP 65.
The fuel meters are designed for horizonal, vertical or diagonal installation.
Optionally, the models of fuel meters can be equipped with the Reed sensor for remote data reading (series RV).
The fuel meters can additionally be equipped with the pulse outputs for remote data transmission in more advanced automated management systems (series IN).
The models of fuel meters with the index А are designed for differentional measurement. They are supplied in pairs. The pairs are specially selected on the plant for more accurate fuel measurement.
