Reliable flow monitoring in oil and lubrication circuits depends on a measuring principle that can handle viscosity without constant compromise. This transmitter family uses a gear volumeter principle for oil and other non-aggressive, lubricating fluids, covering measuring ranges from 0.02...150 l/min in nominal diameters from DN 8...DN 25.
Two intermeshing gears rotate with the flowing medium, while a sensor positioned outside the flow chamber generates pulses for defined measured volumes. The volumetric method keeps viscosity influence low, with use up to 40,000 mm²/s (cSt). With no magnets in the flow chamber and bidirectional operation for most nominal diameters, the device supports dependable monitoring of demanding viscous media.
Integration is straightforward in industrial systems. IO-Link enables configuration and measured value readout, while selectable analog outputs and a configurable push-pull output support control and monitoring tasks. No inlet or outlet sections are required, the connections are pluggable and rotatable, and ingress protection (IP) IP65 / IP67 supports use in typical industrial environments.
Two intermeshing gears rotate in opposite directions as the medium flows through the device and generate defined measured volumes.
A sensor positioned outside the flow chamber detects movement and generates a flow-proportional pulse signal.
The device supports bidirectional operation, with flow direction detection and directional totalizing except for DN 8 variants.
The electronics provide selectable current or voltage analog outputs and a push-pull transistor output with configurable functions.
IO-Link Revision V1.1.3 supports digital configuration and readout of measured values and further data.
The family covers DN 8...DN 25 with G 1/4...G 1 internal threads and aluminum or stainless-steel body versions.
Wetted parts include aluminum or stainless steel housings, stainless steel gears, Iglidur X bearings and FKM seals.
Connection is made via a 4-pin M12x1 circular connector with 18...30 V DC supply.
