The EFH03 Digital Flow Meter for Hydraulic Oil is an integrated digital high-precision volumetric flow meter with an accuracy of ±0.5%, a flow range of 10-30 mL/min, and ModBus RTU output.
The EFH03 utilizes the volumetric principle to dynamically monitor the flow rate of liquids (such as hydraulic oil). Its measurement accuracy is unaffected by changes in oil quality or vibration. It can display instantaneous flow rate, cumulative flow rate, and total time. It can connect to a controller via a standard Modbus protocol output through an RS485 interface and is widely used in flow measurement and monitoring.

Flow monitoring of hydraulic oil is crucial. The Digital Flow Meter for Hydraulic Oil supports ModBus RTU output, facilitating user integration for flow monitoring. Besides the product shown on this page (10-30 mL/min), we also offer other Digital Flow Meters for Hydraulic Oil with an accuracy of ±1% and a range of 0.16-7.5 L/min (10~450 L/H). These output pulse signals, when paired with a flow totalizer, can display instantaneous flow, cumulative flow, total time, etc. When used with a transmitter, it can connect to a controller via a standard Modbus protocol output through an RS232 interface. It is widely used in flow measurement and monitoring.
