Gear wheel Flow-meters, VZB-Series, Q= 0,04- 120 L / min.

Gear wheel flow meters, Gearwheel flow sensors are ideal for hydraulic fluids, engine or lubricating oil, and are used for flow measurement and batching in engine test applications, blending systems and chemical plants for measuring acids, detergents, caustic solutions use VZB-PP or VZB-PE up to 120 LPM.


The Gear wheel Flow Sensors uses two toothed meshed gears that are in shape and engage each other in a precision machined body.

This fluid is transferred sequentially from the inlet to the outlet and one ore more pulses are transmitted for each revolution of the gear.

Embedded within the gear, a pair of chemically resistant magnets provide the external signals.

Detection of the rotation uses either a reed switch or a Hall effect sensor on the outside of the fluid housing.

A choice of materials, PP, PE /  Aluminium allows the meters to be used in a variety of corrosive applications, for non corrosive we use coated aluminum.

The equipment is suitable for use in hazardous areas, and the basic meter is classed as simple apparatus, enabling use in monitoring flows of low viscosity hydrocarbons, fuels and solvents.

B.I.O-TECH can supply electronic metering systems, transmitters and indicators for any application.

Gear Flow meters VZB-Series is avialible with connector protection class IP 65, cable, PLC-compatible digital / analog signal output or Reed-contact. 

The  max. pressure is 110 bar and max temperature up 160 °C.
