Product features
■Easy installation, high flexibility, a pair of sensors can be used for general pipe diameter.
■High accuracy (±0.5%), high reaction speed (sampling speed up to 300 times/s), low velocity measurement (maximum velocity up to 0.03 m/s).
■Single medium can be measured, can be widely used in water treatment, pure water, ultra-pure water, petroleum and chemical industry, air conditioning energy saving and other fields.
■Ordinary standard plug-in sensor cap a temperature of 130 ℃, and the upper limit of temperature 180 ℃ high temperature sensors.
■It can be extended to energy meter to measure energy consumption.
Measuring principle
Ultrasonic time difference measurement method refers to the measurement method of the fluid flow in the same stroke of the flowing fluid, which determines the average flow velocity along the flow direction by using the time difference of the propagation time of two ultrasonic signals traveling forward and backward.
