Precision Measurement System for Trade Settlement of Industrial Large Users
(1)System Composition: Degao's Industrial Large User Trade Settlement Precision Measurement System consists of the following three parts:
① High temperature long life, high precision, wide range electromagnetic water meter
② Remote centralized meter reading module: 4G module, NB-loT module
③ Degao's water supply management system
(2)System Functions:
The precision metering system for trade settlement of industrial large users is an integrated management platform tailored by Degao's for the actual management mode of large-diameter water meters of water supply enterprises, mainly including:
① Degao's industrial large user trade settlement electromagnetic water meter
② Remote centralized copying platform
③ Meter management function
④ Statistical analysis function, etc.
Among them, Degao's electromagnetic water meter is a fully intelligent electromagnetic water meter developed and developed by our company with advanced technology, with high measurement accuracy, stability and reliability; it is extremely meticulous and strict in eighteen core process links such as product structure, material selection, manufacturing process, production assembly and factory testing. Core technologies include:
① High-precision electronic converter independent research and development production,
② Unique small flow measurement technology, ultra-wide range
③ IP68 full waterproof process,
④ Micro-power consumption battery long life,
High accuracy, maintenance-free advantages.

(3)Core advantages:
1 . High precision:
Accuracy: (DN40-DN1200) ≥ 0.3m/s , ±0.2%R, ≤ 0.3m/s, ±1mm
2. high reliability
Degao's electromagnetic water meters are equipped with lightning surge protectors developed to protect the meter from lightning strikes (suitable for 220V power supply)
The zero point of Degao's electromagnetic water meter is very stable and rarely maintained. It can ensure that the instantaneous flow rate is zero without water consumption, avoiding the charging dispute caused by this.
3. Degao's special food grade lining
In response to the water company's request, the lining of intelligent electromagnetic water meter must be environmentally friendly, hygienic and meet the requirements of food grade. Our company has created hydraulic PTFE lining, this hydraulic PTFE lining compared to the traditional rubber lining, PTFE lining has the following advantages:
① Beautiful appearance, smooth, no seams.
② High density, negative pressure resistance, not easy to curl edge.
3. The comprehensive performance of the liner can be compared with that of the expensive Teflon FEP material.
④ Food grade applications can be achieved.
4. With pressure measurement, synchronous acquisition with flow, synchronous analysis; the core circuit board adopts military quality low-noise, high-precision components, which can maintain high-precision measurement at low flow rates for a long time.
5. It can be measured in both directions, applicable to multi-channel water inlet cells.
6. It can solve the problem of high precision measurement of complex working conditions: even if there are trace bubbles and pulsating flow in the pipeline, it can obtain stable measurement.
7. Support 0.002m/s ultra-low flow rate measurement (specially customized for zone measurement), small flow measurement is excellent, is the first product of high-end trade settlement.
8. Super anti-interference
Strong anti-electromagnetic interference ability, in a strong electromagnetic environment, can ensure accurate measurement. In case of serious interference sources such as frequency converters and water pumps, the meter can still be used normally.
9. Lithium battery life is long
Electromagnetic water meter adopts ultra-low power consumption design to ensure battery life of more than 6 years.
10. Optional meter reading mode
DG-FW series electromagnetic water meter can be equipped with 4G/NB-lot module for remote meter reading, or 485 module can be directly connected to the customer's industrial control system for meter reading.
11. Meter reading frequency can be customized according to customer requirements
① 4G module is used for remote meter reading, which can collect data every 15 minutes and upload data up to 6 times a day. (Flow pressure remote transmission integrated installation)
② NB-loT module is used for remote meter reading, which can collect data every 15 minutes and upload data up to 12 times a day. (Flow pressure remote transmission integrated installation)
③ 4G/NB-lot module is used for remote meter reading, which can collect data every 5 minutes and report data every hour. (Sensor, converter separately mounted)
12. Report every change
DGS-1000 series electromagnetic flowmeter has powerful alarm function: battery power, water limit, mutation, non-full tube can be changed alarm, can timely find large users water abnormal.
13. Submersible design
DGS-1000 series electromagnetic flowmeter IP68 submersible design, can work underwater for a long time.
