Rate Transmitters VHZ Gears
VHZ flow rate transmitters are designed for flow measurements with viscous liquids. The fluid passing through a calibrated orifice moves a gear couple. Its rotation is proportional to the delivery and is registered by a Hall type preloaded sensor. The volumetric functioning principle allows a functionality that is independent from the examined fluid. An optional observatory allows to visualise the fluid passage.
Use / Characteristics
 
- Assembling in any position.
- Independence from viscosity because of a volumetric functioning principle.
- Measurement range 1:100 starting from 0,1 l/min.
- Good precision ±3%.
- No magnetic parts in the measurement chamber.
 
These instruments are mainly used in the field of oil-hydraulics and lubrication to control circuits with oil flow, i.e. oildynamic control units of the hydraulic pistons, mechanical transmissions, typographic machines, etc. Transmitters are fit to operate on fluids with lubricating properties.
