CONTOIL ® VZO 4 OEM / VZO 8 OEM Special Edition

Flow meters without roller counter with magnetic reed pulse sensor. Measured value indication is performed on the remote display. These meters are designed for installation in fuel systems, where limited or impossible to read the measurement.

This series of meters has been widely used in combination with the navigation systems on the vehicles and in remote monitoring of fuel consumption on stationary objects (diesel generators, fuel oil burners, etc.). The data comes from the meter through the controller to the transmitting device (technology GPS, GSM / GPRS, Bluetooth, GLONASS, etc.), and then to the management company’s PC.

Possibility of horizontal, vertical or diagonal installation.

Instruments are supplemented with protective aluminum cover and the two connecting cables (4 meters) and with convenient connections.
