Intelligent multi-flow water meter (valve controlled)

Description

Implementation standard: GB/T 778 Measurement of water flow in closed full pipeline Drinking cold water meter and hot water meter JJG 162-2009 Cold water meter

二、Working Principle

The intelligent multi-flow IC card water meter adopts the intelligent multi-flow principle. It is a kind of water meter that further calculates the flow rate of water by analyzing and processing the time difference caused by the change of speed when the intelligent multi-flow sound beam propagates downstream and countercurrent in the water.

Performance characteristics

1. There are no moving parts in the meter body of the intelligent multi-flow IC card water meter. Mechanical wear can be used stably and reliably for a long time, and the measurement accuracy can be maintained for a long time.
2. The intelligent multi-flow water meter has a large range ratio and a small starting flow rate, and the range ratio of the water meter can reach: R80 ~ R160; The initial flow rate of the water meter can be as small as 15 liters per hour.
3. The metering accuracy of the intelligent multi-flow IC card water meter is after the end, but the factory inspection can be required according to the Level 1 accuracy standard.
4. Intelligent multi-flow water meter has strong adaptability to fluid temperature changes and can achieve T30/T50/T70 temperature grade.
5. The intelligent multi-flow water meter has strong antistatic and anti-magnetic interference capabilities, and the antistatic can reach more than 12000V V.
6. The intelligent multi-flow water meter adopts micro-power consumption design technology to minimize the comprehensive power consumption of the water meter and has a service life of more than 6 +2 years.
7. The intelligent multi-flow water meter has the function of long-term data storage, which can realize annual, monthly and daily data storage and recording, which is beneficial for the management department to analyze the big data of water use and make reasonable water use decisions.
8. The intelligent multi-flow water meter has a water flow direction identification mechanism, which can measure forward and reverse flow, and can adopt a variety of forward and reverse flow statistics and display methods so as to use units for data analysis.
9. The intelligent multi-flow water meter has an alarm mechanism for long-term water running (leakage alarm) and an oath reporting mechanism for a single water running exceeding a preset amount, which can timely remind users whether there is water leakage in the household water pipe and whether they forget to turn off the faucet.
10. The intelligent multi-flow water meter has an empty pipe alarm mechanism, which can be used as an abnormal disassembly alarm after a long period of normal water running.
11. The intelligent multi-flow water meter has an error counting (instantaneous excessive flow metering) judgment mechanism. When an error counting occurs, it can alarm in time and record the error time. When an error counting occurs, the MCU software in the meter has an error correction mechanism, which can prevent the occurrence of an error counting to the greatest extent.
12. Intelligent multi-flow water meter has the function of measuring fluid water temperature, and can give low temperature or high temperature alarm, so that the management department can deal with it in time.
13. The combination of intelligent multi-flow water meter and management system can have a family water care mechanism. When the family children are not with the elderly, the children or the community where the elderly are located can know the water habits of the elderly through mobile phone APP, which can give early warning in time.
14. The valve-controlled intelligent multi-flow water meter has a valve control function. When the amount of water purchased is insufficient, the valve will be automatically closed. Afteraccountrecharged and swiped, the valve will be automatically opened. In addition, the corresponding valve opening and closing conditions can also be set in the water meter to execute the corresponding valve action.
