Model 3050 together with flow sensors of series 200 or SDI series offer an excellent unit for energy consumption monitoring in many buildings which are centrally controlle. HVAC processes in residential or large complexes as well as bis industrial processes can be monitored.
The series feature a six-bladed impeller design with a proprietary, non-magnetic sensing mechanism. The impeller shape coupled with the absence of magnetic drag provides accuracy and repeatability throughout the flow range of the sensors. As the liquid flow turns the impeller, a low impedance square wave signal is transmitted with a frequency proportional to the flow rate.
