Electromagnetic Water Meter
ZLINK electromagnetic water meter is a flow measurement system composed of electromagnetic flow sensor and converter. It is mainly used in large user trade, community assessment, secondary water supply, zoning measurement and other water occasions, with wide range, low initial flow rate, high precision and other characteristics, widely used in water flow measurement in places without power supply.
Feature:
| Measurement Range |
R: 160/250/400/630 |
| Long Battery Life |
Built-in Lithium battery, 12 years battery life for theory to make sure to work for |
| IP68 Design |
Satisfy the environmental requirement of underground laying of pipe. |
| Adaptable Frequency Measurement Adaptive Frequency Conversion Measurement |
Under the condition that the battery life is fully guaranteed, when the valve is detected, the valve is closed or the flow mutation, the paid measurement will be started once 1s, lasting for one minute. |
| Anti-+broken Design |
All fixing screws are completely hidden, and the sealing of the outlet holes is processed to prevent man-made damage. |
| Respond to Changes |
When there is alarm information, it is not limited by the upload time interval, and the information is immediately sent to the platform. |
| Precision Class |
Class 1, Class 2 |
| High Reliability |
There are no moving parts inside the sensor, long-term measurement will not appear wear, anti-interference design is adopted to ensure long-term stable operation of the water meter. |
| Low Starting Flow Rate |
In operating mode, the starting flow rate is 4mm/s, further reducing water loss. |
| Data Transmission |
Through GPRS, NB-IoT, RS-485 etc. to read instantaneous flow rate, cumulate flow rate and other relevant data. |
| Pressure Measurement (optional) |
The pressure sensor can be selected for pipeline pressure test, and the operation of the pipeline can be analyzed from the pressure data. |
