​IMPELLER FLOW METER:Impeller Flowmeter: Different size impeller cages can be interchanged to suit different pipe or bore hole diameters.

​SPECIFICATIONS:Weight / length: 3.5kg / 0.48mCage Diameter: Optional interchangeable impeller       cage sizes to order.Typically: 50, 70 and 100mmThreshold Velocity: Varies with cage size. (Typically       1 m/min with 50 mm cage)Resolution: 1/40th turnData output Flow rate, directionMax. Pressure: 20MPaMax. Temp.: 80ºC                                      

​HEAT PULSE FLOW METER:This sonde is used for applications where the flow rate is below the threshold of the impeller. Flow meter probes can be used independently or in combination with other sondes.
