Small flow metering
Pipeline leakage is a thorny issue for most water companies one of the important reasons for the high production sales gap in water supply. By analyzing the small flow rate at night, it can reduce the leakage rate, assist the water company in reducing the production sales gap, improve work efficiency, achieve turning losses into profits.
At night, when the user's water consumption is low, the quantitative leakage is accurate.
At present, the current water supply situation of most domestic water companies is that the design of pipelines on the pipeline network is too large, resulting in very low flow velocity inside the pipeline, especially at night.
High measurement accuracy of electromagnetic water meters for intermittent water users
Frequently closing opening the pressurized system can seriously affect the structure stability of the water supply network, so continuous water supply is a good choice for any water supply company. However, some networks can only provide intermittent water supply, which requires the initial flow rate (also known as sensitivity) of the measuring water meter to be small the reaction ability to track flow changes to be good.
Our company's newly developed electromagnetic water meter has a sampling cycle of 1 second in the normal metering mode for users, which solves the problem of inaccurate metering for intermittent water users makes real-time measurement of electromagnetic water meters possible.
Straight through structure without any reduction in diameter
The electromagnetic water meter measurement pipeline is a straight pipe, which can ensure that the water meter range ratio reaches R400 above without any reduction in diameter. This only reduces the power consumption of the pipeline system, but also meets the customer's demand for high range ratio measurement.
Report every change
The electromagnetic water meter has a powerful alarm function: the battery level, water volume exceeding the limit, sudden changes, non full tube can all be alarmed in case of any changes, can promptly detect abnormal water usage for large users.
Very low initial flow rate
The electromagnetic water meter can reach a starting flow rate of 2mm/s, can be measured by dripping water. The accurate measurement of nocturnal small flows by zones is of great significance.
All stainless steel submersible design for the entire machine
The entire electromagnetic water meter can be designed with all stainless steel has an IP68 protection level. In addition to a clean floating appearance, the instrument can operate reliably under complex working conditions such as underwater all year round.
Food grade lining
The electromagnetic water meter adopts a food grade rubber lining to ensure that the drinking water quality meets the requirements.
anti-interference
Strong resistance to electromagnetic interference, ensuring accurate measurement in strong electromagnetic environments. When encountering serious interference sources such as frequency converters water pumps, the meter can still be used normally.
Lithium batteries have a service life of over 6 years
The electromagnetic water meter converter independently developed by our company has a static power consumption of only 400 microamps on the circuit board, which can ensure a battery life of more than 6 years for the water meter.
Zero point is very stable
The zero point of the electromagnetic water meter is very stable rarely maintained, which can ensure that the instantaneous flow rate of users is zero when they are using water, avoiding fee disputes caused by this.
High precision stable measurement
The water meter converter is independently developed by the company uses military quality low noise, high-precision imported components, which can maintain high-precision measurement at low flow rates for a long time. High performance excitation method optimized filtering algorithm can ensure fast response high-precision measurement, even when there are trace bubbles pulsating flow in the pipeline, stable measurement can be obtained.
Good compatibility of meter reading system
The meter reading system is compatible with other domestic manufacturers' remote meter reading systems, avoiding customer resource waste.
Can be equipped with pressure measurement (integrated installation of flow pressure)
Multi parameter monitoring IoT technology can simultaneously detect pipeline pressure, flow, etc.
Patent anti disassembly design
The patented anti-theft detachable meter cover will alarm once the meter seal is opened to prevent theft tampering with instrument data.
Optional meter reading method
The electromagnetic water meter can be equipped with 4G module NB loT module for remote meter reading, 485 module can be directly connected to the customer's industrial control system for meter reading.
4G remote meter reading frequency
The integrated electromagnetic water meter can upload data 12 times a day, which can meet customers' requirements for meter reading frequency.
NB loT remote meter reading frequency
The integrated electromagnetic water meter adopts our company's NB loT module, which can upload data 24 times a day
lcd
The electromagnetic water meter screen is equipped with backlight, which can manually read instrument data under strong light. (Optional OLED display screen)
Seamless Switching Technology between Municipal Power Supply Lithium Battery Power Supply
The integrated electromagnetic water meter can achieve dual power supply of 220V 3.6V lithium batteries. When the mains power supply is suddenly cut off, the instrument will automatically seamlessly switch to lithium battery power supply without affecting metering.
The remote RTU module has Bluetooth function, which can achieve data supplementary reading
Once the water meter installed in the underground well encounters weak base station signals poor network communication, the success rate of meter reading will be greatly reduced. RTU Bluetooth can remotely control the APP to achieve data supplementary reading
Installing an app on a phone with Bluetooth allows for maintenance of the RTU.
