Wall Mount Ultrasonic flow meters - Overview

Ultrasonic flow meters operate by alternately transmitting and receiving a frequency between two transducers and measuring the time that it takes for sound to travel between the two. The difference in the transit time is directly and accurately related to the velocity of the liquid in the pipe. This wall mount ultrasonic flow meter is designed for use in a closed conduit. The transducers are clamp-on types, which in turn makes for easy installation and operation.

Modular Ultrasonic Flow Meter - Overview

This Ultrasonic Flow Meter is compact and economical. It works using the transmit-time working theory. One ultrasonic sensor sends an ultrasound wave, and another sensor receives this wave. The transmit time from send to receive has a direct relationship with the flow speed. The converter then calculates the flow speed based on the transmit time. It can easily be installed onto an instrument box via DIN rail. It has no pressure loss, and measurement is not affected by temperature or pressure changes. Accuracy can reach ±1%. It has an LCD display and communicates via 4-20mA, pulse or RS485 outputs. It also has reliable empty/full tube detection technology. Excellent low flow rate measurement performance. Turndown ratio 100:1.
