Small online Size Ultrasonic Flow Meter RTU High Accuracy For Liquid Measuring
Introduction
Ultrasonic flow module/RTU is widely used for various kinds of liquid measuring. The host adopts
rail installation, sensors are installed on pipe. They are contacted by a special cable. It can measure flow, also can measure heat if contact temperature sensor.
It can be used in system integration, water resource, energy conservation applications, etc.
Features
1%
Several types transducer for selection, pipe size from DN15mm to DN6000mm
Adopt low voltage, multi-pulse technology to improve accuracy, operation life and reliability.
Dual-balance signal differential receiver/driver circuit to avoid interference of converter, TV tower,high voltage line etc.
1 way 4-20mA, as a flow sensor or quantity of heat sensor; 2 way OCT output, as a switch for flow/ quantity of heat; 3 way 4-20mA output, as s collector for data; 2 way 3 wires is PT100 signal output of resistors, as a watch for quantity of heat.
RS485 support connect wireless net, contact the GPRS485 can realize wireless transmittal.
Connect the temperature transducer ,can finish the heat/energy measurement
