| Description |
The threaded ultrasonic BTU meter is designed for measuring thermal energy of small area where pipe size is not bigger than 40mm , e.g. apartment, villa, shop, etc. The BTU meter comprises of ultrasonic flow sensor and two temperature sensors, base on flow rate and differential temperature of supply / return water to calculate the thermal energy consumption. The product adopts a design of straight-through pipe, features with high measurement accuracy, low pressure drop, anti-blocking, stable operation and long service life. The product can be widely used in central heating/cooling and district heating/cooling systems for thermal energy measurement of residential, commercial and office building.
– High-quality fully enclosed ultrasonic element ensure accuracy and stability of flow measurement
– Using high-quality PT1000 temperature sensors, calibrated and matched to an accuracy better than +/- 0.1 ° C.
– Casing protection class IP68.
– Can be installed horizontally or vertically, and the head is detachable.
– With M-bus / Modbus protocol interface, compatible with BMS for remote reading function. RS485 is optional.
– Detachable battery case for quick replacement.
– Can be mounted on supply or return pipe (specify when ordering);
– Can be used for both heating and chilled water.
