Central air-conditioning energy meter

Central air-conditioning energy meter Tel: 13915191836 central air-conditioning energy meter Product description: 1. Central air-conditioning energy meter is the use of ultrasonic flow transducers and temperature sensors for measuring water flow and return water temperature difference so that measurement and display flow through the heat exchange system release or absorb heat meter. 2. Use the measuring principle, address the pipe pressure instability, water hammer, pulse accumulation phenomenon caused by jitter, and more without worrying about magnetic attacks fundamentally stable and reliable. 3. Use the measuring transducer, straight pipe section is integrated structure, measuring mechanism with no moving parts, so there is no wear, measurement accuracy is not using cycle impact. The test system has no moving parts, thus greatly reducing the pressure loss. Long life, especially for high impurity content of the water quality. 5. The instrument designed for BAN heating piping design, can be installed at any angle, when the magnet interference, instrument measuring unaffected. 6. The power supply with 3.6V battery, a battery life of up to six years, to avoid the field wiring trouble. 7. Ultra-low-power design, power-saving mode automatically when the empty tube. 8. multifunctional alarm indicator, convenient post-maintenance. 9. equipped with M-BUS communication function, which enables remote meter reading, also optional RS485 communication. 10.18 month history storage for users to query 11 can be installed at any angle, to facilitate construction. 12. The display header can be adjusted on all sides, removable from the meter body operation. 13. Scope: public buildings, BAN measurement, heat exchange station heat metering, heat metering, central heating (cooling) heat metering system, a variety of the total heat distribution method of measurement. Central air-conditioning energy meter Stainless steel or steel nominal diameter (mm) DN15 ~ DN3000 Measurement Range Temperature Range (℃) -30-160 ~ 95 (factory default, beyond this range, made when ordering) Minimum pairing temperature error (℃) ± 0.1 Communication Type RS-485, the main display 10 digital + prompt LCD accumulation of heat MW · h or GJ, thermal power MW; power, flow rate m3 / h, cumulative flow m3, water temperature ℃, return water temperature ℃ , temperature K, the cumulative operation time h Date: Year / Month / Day, Clock: hour / minute / second cumulative calories display range: 0 ~ 999999.99MW · h.
