ONICON F-4200 Clamp-on Ultrasonic Flow Meters offer an ideal solution for liquid measurement in existing systems when it is impractical to install traditional inline or insertion style ﬂow meters. The innovative design incorporates matched precision clamp-on transducers and signal processing circuitry to accurately measure the ﬂow of most liquids over a wide velocity range. Each F-4200 is provided with transducers and easy-to-use mounting hardware, factory supplied transducer cabling and a wall mount enclosure with an LCD and user interface keypad.
Output signals include a 4-20 mA analog signal, a scaled pulse for totalization, and a relay output for indication of ﬂow direction or alarm status. The F-4200 is also provided with an isolated RS485 output capable of communicating over BACnet MS/TP or Modbus RTU networks. Optional BTU measurement systems are also available.
