Ultrasonic Open Channel Flow Meter

Ultrasonic flow meters measure the level in a channel by transmitting a pulse of sound from the face of the sensor to the surface of the flow stream and measuring the time for the echo to return.

Ultrasonic open channel flow meter.

The transit time corresponds to the distance between the face of the sensor and the surface of the water. The flow meters use a non contact level sensor to detect the water level and then calculates the flow rate and volume using the manning equation and characteristics of the channel. An economical open channel flow meter isonic 4000 measures level flow rate and total volume of water flowing through weirs and flumes. The third type is the open channel flow meter.

The sitrans probe lu240 is a 2 wire loop powered ultrasonic level transmitter bringing you the reliability of sonic intelligence echo processing. The meter includes a non contact ultrasonic level sensor to detect the water level and then calculates the flow rate and volume using the manning equation and characteristics of the channel. Principle time transit flow meter. Ultrasonic flow meters measure the difference between the transit time of ultrasonic pulses propagating with and against the flow direction.

Ultrasonic flow meters that use the doppler shift are called reflection or doppler flow meters. Our ultrasonic flow meters are perfect for wastewater applications they present non invasive flow meters that measure and determine velocity of fluid in a pipe. Open channel flow meters measure level flow rate and total volume of water flowing through weirs flumes channels and partially filled pipes. Non contacting velocity measurement is also available for use in open channel flow for velocity x area measurement.
