MEGA-H1 Residential Ultrasonic Heat (Cooling) Meter is a new type of heat meter which based on ultrasonic transmit-time, constituted by the flow sensor, the temperature sensor and deposition of the instrument, related to the principle of heat measurement, temperature sensors, flow sensors, digital communication technology systems, and computer chip technology.

• Internal high capacity 3.6V lithium battery;
• The unique construction of the arithmetic unit allows a tilt of 0°-120 ° and rotation of the housing from 0°-350 °. This enables the user to read the data from different angles;
• Can be mounted on supply or on return pipeline and can be mounted in either horizontal or vertical direction. The use of ultrasonic technology allows installation angle-independent.
• Compatible with CJ/T 188, MODBUS RTU, EN13757 communication protocol;
• Support optical IrDA, pulse output, RS485, wired & wireless M-Bus Interfaces;
• The product conforms to European MID and Chinese CMC certification in line with the European EN1434 and Chinese CJ128-2007 standard. Compatible to the German Heating Association Measurement NOWA protocol.
