Intelligent multi-flow meter is used to realize accurate measurement of flow. The product has the characteristics of beautiful appearance, convenient installation, accurate measurement, stable operation, strong anti-pollution and anti-corrosion capability, long service life, small pressure loss, economy and practicality, etc. It is suitable for flow metering and charging of domestic water, central air conditioning system water, etc.
Working Principle
The intelligent multi-flow meter adopts the principle of intelligent multi-flow. 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 counter current in water.
Performance characteristics
1. There are no moving parts in the intelligent multi-water meter body, mechanical wear can be used stably and reliably for a long time, and measurement accuracy can be maintained for a long time.
2. The intelligent multi-water meter has a large range ratio and a small initial 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 meter is the same, but the factory inspection can be required according to the Level 1 accuracy standard.
4. The intelligent multi-water meter has strong adaptability to fluid temperature changes and can achieve T30/T50/T70 temperature grade.
5. The intelligent multi-water meter has strong antistatic and anti-magnetic interference capabilities, and the antistatic can reach more than 12000V V.
6. The intelligent multi-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-water meter can choose a variety of communication modes, such as NB-IOT. LoRa, LoRaWAN, M-Bus. RS485, pulse and other communication modes, and is equipped with infrared communication mechanism, through which instrument parameters can be configured or instrument data can be read.
8. The intelligent multi-flow meter has the function of long-term data storage, which can realize annual, monthly and daily data storage and recording, which is beneficial for management departments to analyze water consumption big data and make reasonable water consumption decisions.
9. The intelligent multi-flow 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.
10. The intelligent multi-flow 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.
11. The intelligent multi-water meter has an empty pipe alarm mechanism, which can be used as an abnormal disassembly alarm after normal water running for a long time.
12. The intelligent multi-flow 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.
13. The intelligent multi-water meter has the function of measuring fluid water temperature, and can give low-temperature or high-temperature alarms so that the management department can deal with them in a timely manner.
14. The combination of intelligent multi-water meter and management system can have a family water care mechanism. When the children of the family are not with the elderly, the community where the children or the elderly are located can know the water habits of the elderly through mobile phone APP, which can give early warning in time.
15. The valve-controlled intelligent multi-flow meter has a valve control function. The control of valve opening and closing can be executed by issuing corresponding commands through wireless communication. In addition, corresponding valve opening and closing conditions can also be set in the water meter to execute corresponding valve actions.
