The UL33oO ultrasonic flowmeter based on the time difference method is independently developed by our company by drawing on the advantages of various foreign flowmeters. This ultrasonic flowmeter is a flow velocity and flow rate measurement instrument made based on the principle of the "time difference method" of ultrasonic waves. This product has no rotating parts such as propellers and bearings. It uses ultrasonic technology to detect flow velocity, with no friction and no inertia. The underwater sensor is small in size and does not disrupt the flow field. It features high measurement accuracy, wide measurement range, high sensitivity, linear flow measurement, and is not easily damaged. It has unparalleled low flow velocity and shallow water measurement capabilities, capable of measuring the minimum flow velocity of O.O1 meters per second and the shallowest depth of 5 centimeters in small streams. Additionally, it can be equipped with modules according to customer requirements to achieve other functions (such as Bluetooth, GPRS, GPS communication, etc.).
This product is applicable to various fields such as testing institutions, laboratories of scientific research institutions, and flow velocity and flow measurement of all kinds of streams and rivers. It is the best measurement tool for environmental monitoring and hydrological applications. This product can be connected to the Internet of Things via GPRS and Wi-Fi.
