Description:

Integrated IoT valve-controlled ultrasonic heat meter is a new ultrasonic heat meter that measures and displays flow based on the ultrasonic time difference principle. It adopts an integrated structural design and integrates a data remote transmission interface (optional M-BUS/RS485/4G/LORA/NB-IOT, etc.). Through the data remote transmission interface and other communication equipment, a remote meter reading management system can be formed. Managers can read the data in the meter at any time, which is convenient for users to count and manage heat.

Features:

Undervoltage alarm
Automatic data error correction
Temperature sensor fault alarm
Flow sensor fault alarm
High-definition wide-temperature LCD
Battery life of more than 6 years
Remote control of valve on and off
On-site meter reading using infrared meter reading tools
