Schematic Diagram of the Zonal Water Supply Metering System
|
| |
| System Working Procedure and Functions: |
| The quantity of make-up water between 2 adjacent zones is first measured with the SCL-73xLL 2-way ultrasonic flowmeter, |
| a meter capable of making measurements of flowrate of water flowing in either a forward or reverse direction. The measured |
| data is then sent via GSM network to the center-end computer to calculate the actual water supply quantity in individual zones, |
| with the use of the zonal metering and management software. Through comparisons made between the actual water supply |
| quantity and the reported data, the loss of supply water in each zone caused by pipe leakage or illegal use of water by improper |
| means can be identified. This may help enhance the management level of water supply enterprises, improve their economic |
| performance and save the water resources. |
| Technical features: |
| 1.It is capable of metering the water flowing in a forward or reverse direction with the use of the 2-way transducers. |
| 2.It is battery powered, making it possible to be used on site where external power source is unavailable. |
| 3.It can be on-line mounted under the pressure of water flow, eliminating, therefore, the trouble caused by shutdown of water flow. |
| 4.Thanks to the use of the insertion-type dual-transducer, the ex-factory calibrated accuracy and that after site mounting can be |
| fully ensured. |
| 5.It is highly sensitive to an extremely low initial flowrate even at a small water supply flowrate. |
| 6.Its use may lead to reduction of meter well construction costs because of less requirement on meter mounting space. |
| 7.Various output interfaces are available for selection and wireless data transmission can be made via GSM network. |
| 8.The integral (one-piece) meter version and the GSM communication receiver can work stably over a long period of time in meter |
| well with a protection class of IP68. |
