Meters and Measurement Devices for Exact Consumption Data Acquisition

The ultrasonic heat meter, 250 series (brass, threaded type) integrates the heat meter and valve. Only one set of software is required to realize the functions of billing, remote monitoring, prepayment and overdue cut-off. This handles the practical problems encountered in heating system management and billing to a great extent.
