Overview
The Enviro Testers Clamp-On Ultrasonic Flow Meter with Wireless IoT Communication is an ultrasonic liquid flow meter designed using the principle of time difference. It can obtain the flow rate in the pipeline by measuring the time difference between upstream and downstream transmission and is suitable for pipelines between Ø6 and Ø110mm.
The Enviro Testers uses advanced integrated circuit technology, which can effectively achieve the design principle of anti-noise, high accuracy, and low energy consumption, and has RS485 Modbus (RTU), 4 to 20mA, OCT (NPN), Relay output, and can also be selected LoRa, NB-IoT wireless communication function, which has a wide range of use and can meet the needs of customers for traffic detection.
Features
