This series is a positive displacement gear flow meter for precise continuous or batch measurement of liquids in pipelines. A pair of meshing gears rotates in a precision-machined chamber; each revolution transfers a fixed volume, and the gear rotation is picked up magnetically to give instantaneous and totalized flow.
Within its specified range the measurement is practically independent of viscosity, which makes it well suited to oils, resins, polyvinyl alcohol and other viscous media, as well as small flow rates. No upstream or downstream straight pipe runs are required.
Key features
- Volumetric (gear) measuring principle, ±0.5 % of reading, repeatability ±0.05 %
- Accuracy unaffected by viscosity within the specified range; suited to highly viscous media
- Stainless steel body rated 40 MPa; aluminium alloy body for 2 MPa
- Wide temperature range, -60 to +150 °C
- Low pressure drop and low noise; no straight pipe runs required
- Pulse, 4 to 20 mA and RS485 (Modbus RTU) outputs, with optional local LCD (instantaneous and total flow)
- Volume or mass flow display (with density setting), selectable flow units
