Product introduction
KL88 series ultrasonic flowmeter/calorimeter is a kind of universal time-difference ultrasonic flow measuring instrument based on similar foreign products, which is widely used for uninterrupted measurement of clean and uniform liquid flow and heat in industrial environment. With strong adaptability, low power consumption, high reliability, anti-interference and optimized intelligent signal adaptive processing ability, no circuit adjustment, simple and convenient operation. The good circuit design concept and the selection of high-quality devices have gradually replaced the early similar products and become the most widely used flow metering instruments in China.

Product advantage
The hand-held, external clamped, ultrasonic flowmeter realizes the non-contact measurement of liquid flow, and the sensor is installed on the outer wall of the pipeline to complete the measurement of flow. It has the characteristics of small volume, easy to carry and accurate measurement.
The plug-in ultrasonic flowmeter only needs to be installed in the pipeline under test. The plug-in sensor can be installed in the field without stopping water by using the transmission machine, and the measurement is more stable and reliable because the sensor is in direct contact with the fluid.
The tubular ultrasonic flowmeter has the advantages of simple installation, low initial measurable flow, high measurement accuracy and no pressure loss.
