Central air conditioning billing

Central air conditioning billing Tel: 13915191836 central air conditioning cost Product description: 1. Central air conditioning cost is the use of ultrasonic flow transducers and temperature sensors for measuring water flow and back the water temperature difference, so that measurement and display of the water flowing through the heat exchange system to release or absorb heat meter. 2. Use the measuring principle, address the pipeline pressure instability, water hammer, pulse jitter accumulation phenomenon caused more without worrying about magnetic attacks fundamentally stable and reliable. 3. The use of the measurement transducer, straight pipe sections as a unitary structure, measuring mechanism with no moving parts, so there is no wear, the life cycle of measurement accuracy is not affected. 4. Measure the agency no moving parts, thus greatly reducing the pressure loss. Long life, especially for high impurity content of the water quality. 5. The instrument is designed for BAN heating piping design, can be installed at any angle, when a magnet interference, without any influence of the measurement instrument. 6. The power supply with 3.6V battery, a battery life of up to six years, to avoid the trouble of field wiring. 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, but 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 body operating table. 13. Scope: public building, BAN measurement, heat exchange heat metering, heat metering, central heating (cooling) heat metering system, a variety of the total heat distribution method of measurement. Central air conditioning billing Material Stainless steel or steel nominal diameter (mm) DN15 ~ DN3000 measuring range temperature range (℃) -30-160 ~ 95 (factory default, beyond this range, made when ordering) Minimum pairing temperature error (℃) ± 0.1 maximum allowable working pressure (MPa) 5 (out of this range, made when ordering) Accuracy 2 Pt100 temperature sensor type of protection machine: IP68; split type: lower machine IP68, IP65 and IP68 optional PC work power battery, a battery can work for more than six years. AC220V ± 10%, raised) Power (mW) <0.8 Work environment class B type RS-485 communications DC24V when ordering, the main display 10 digit LCD + prompt accumulation of heat MW · h or GJ, MW thermal power ; power, instantaneous flow m3 / h, the cumulative flow m3, water temperature ℃, return water temperature ℃, the temperature difference K, the cumulative operating time h Date: year / month / day, the clock: hour / minute / second cumulative calories display range: 0 ~ 999999.99MW · h. Display resolution cumulative heat 0.01MW · h or 0.1GJ, thermal power 0.0001MW, cumulative flow 0.1m3, temperature 0.01 ℃, the temperature difference 0.01K. Ambient Temperature (℃) -25 ~ + 55 data storage (EEPROM) monthly storage of heat, and the corresponding cumulative flow time and maximum thermal power of the month, you can store the last 18 months of data.
