 The meter works on “velocity-difference” principle and is specifically designed for urban |
|
| water supply pipeline network and dwelling houses. Its use can effectively overcome the |
|
| knotty problems encountered in the use of a conventional water meter (a conventional water |
|
| meter can only detect a higher flowrate and remains inactive to a small flowrate). The meter |
|
| is also applicable to various industrial applications. |
|
| It operates with ultrasonic flow measuring technology without any moving mechanical parts, |
|
| and is high in reliability, less in maintenance work and immune to any magnet interference. |
|
| It is battery powered capable of working continuously over 6 years with a single battery. As |
|
| no pressure loss is incurred, the power consumption can be drastically reduced. |
|
| The meter is highly sensitive to extremely low initial flowrate and high in accuracy, and |
|
| capable of providing different kinds of outputs. The meter can effect radio transmission of meter |
|
| readings through Connecting with GSM .In this way a tariff control system can be formed for |
|
|
| effecting timely monitoring the operating status of all the meters in use. |
| Single-path, 2-path and 4-path working patterns are available for selection. |
| The meter has 3 versions in design – normal, 2-way and anti-theft versions to better cater to the specific needs of users. |
| The 2-way version can measure a pipe flow in both directions and record the cumulative running time in this case. The model of this version is |
| indicated by adding a suffix (D) behined that of a common version. |
| The anti-theft version has the function to prevent anybody from making free use of water by unfair means. The cumulative water flowrate indicated |
| is the sum of the absolute instantaneous flowrate values of water flowing in both forward and backward directions, making it impossible for anybody |
| to gain economic advantage through illicit use of water without pay. The model of this meter version is designated by adding a suffix (A) behined that |
| of a common version. |
| All the technical data given herein are those of the general type of the flowmeter, yet they are also applicable to the 2-way and anti-theft versions. |
| In conformity with the Standard on Ultrasonic Water Meter Q/TH001-2004 – An enterprise standard formulated by Huizhong. |
| Calibrated according to the regulations on calibration procedures as specified in the same standard as stated above. |
| Without incurring pressure loss and capable of maintaining a long-term stable operation with the water (including fire-fighting water) flowing at a |
| highest flowrate with a strong rushing force. |
