The Ultrasonic Flow Meter

Ultrasonic flow meters enable users to perform flow measurement inspections at many points in the flow process without the need for permanent installation. This universal driving time timer has a dual-function button interface, an ergonomic handheld design, and a beautiful backlit color digital display that greatly simplifies setup and data collection. Compared with other traditional flowmeters or ultrasonic flowmeters, it has the characteristics of high accuracy, high reliability, high performance, and low cost. The flowmeter also has other advantages:

TVT technology design. Fewer hardware components, low-voltage broadband pulse transmission, and low power consumption.

Clear, user-friendly menu selections make the flowmeter easy to use.

Daily, monthly and yearly total traffic. The parallel operation of positive, negative, and net flow is displayed cumulatively by a scale factor (span) and a 7-digit number.
