Ultrasonic flow meter lrf-2000m is a flow module. Users can even integrate a number of the modules into a multi-channel flow meter that can measures up to several dozen of different pipes or a flow meter that has higher accuracy by measures the same pipe with all the channels. The design of the meter is intended to provide for users like system integrators and OEM users with a lowest cost but of high performance flow meter.
Powerful functions: Current output: 4-20ma, one channel, can be used for flow/heat transmitter; Oct output: Two channel, can be used for flow / heat switch; Current input: 4-20ma, three channel, can be used for data collector; Tri-wire resistance signal input (PT100): Two channel, can be used for calorimeter.
Far transmission distance: Connect flow/heat module and secondary meter through RS-485 interface, transmission distance up to 1000m. Solve the problems of high cost of special cable, poor anti-interference, short transmission distance etc.
Wide measuring range: Several types transducer for selection, pipe size from dn 15mm to dn 6000mm
High accuracy measuring: Accuracy: ± 1%, linearity: 0.5%, repeatability: 0.2%
