Open Channel Flow Meter

Open Channel Flow Meter | Ultrasonic Level Meter |  Ultrasonic Level gauge  | Ultrasonic Level transmitter  | Ultrasonic probe
SF-500S with LXD-04

SF-500S is an ultrasonic non-contacting flow meter for open channels. The measured level value is converted into the rate of flow in specific weirs or flumes therefore the accurate level value is very important. LXD-04 sensor is an exclusive sensor for open channel flow, it provides accurate level reading.

SF-500S provides a variety of weirs and flumes formulations so it can be used in different applications. The measured flow information is saved in the memory of SF-500S and it can be downloaded by USB or transmitted by digital communication such as RS232, RS485, or Modbus.
