Overview
Enviro Test Construct Ultrasonic Flow Meter with Data Logger measures fluid velocity within a closed conduit with accuracy, detects virtually all liquids. The new ultrasonic flow meter has been manufactured with patented technologies and is equipped with more functions, providing advanced performance than previous versions.
Version 8 ultrasonic flow meter has been upgraded based on the Version 7 ultrasonic flow meter. The new version retains most of the excellent features and functions of the previous versions. Functions include the pulse measurement technology, the ultrasonic igniting and the small signal receiving of circuits.
The main improvements are made on the battery supply circuit and on the transmitting circuits. All other circuits are simply integrated into this new version without major modifications.
The hardware features easy operation use, high accuracy and outstanding reliability, while the software provides a very user friendly interface with many functions. The flow meter employs the patented balanced lower voltage multi-pulse igniting circuit which increases the anti-interference ability magnificently so that the flow meter will work in demanding industrial environments such as those with power frequency transverses nearby.
