Handheld (portable) ultrasonic flowmeter price manufacturer

The handheld (portable) ultrasonic flowmeter utilizes the principle of low voltage and multi pulse reception and transmission, adopts dual balanced signal differential transmission and reception technology, and hardware independent design method; Produced through the use of the latest and most advanced large-scale integrated circuits and advanced SMD mounting and soldering processes internationally. Ensure that each factory flowmeter has the same performance. Flexible and versatile all Chinese display host (wall mounted F1 standard type, wall mounted F2 explosion-proof type, disk mounted S type, wall mounted FN network type) to meet various industrial sites; The plug-in sensor solves the problem of signal attenuation and scaling on the inner surface of the pipeline due to long-term operation of the external clamp sensor, and can be installed without stopping production. Suitable for various pipelines such as steel pipes, cast iron, fiberglass, PVC, and cement.
