Water Meter Test Bench


Design Standards

•  75/33/EC and 79/830EEC and with standard ISO 4064
•  Meet the requirements of ISO 4064, EN 14154 and OIML R 49 for initial verification tests, and OIML R 75 and EN 1434 for flow sensor initial verification tests.
•  Are designed to achieve maximum accuracy and constructed to comply with the international standard ISO 4185
•  Are designed to achieve a combined measurement uncertainty of less than 0.2% (2 standard deviations) at typical volumes

Methods of Test Bench

•  Weighing method of operation
•  Master meter method of operation

System Features

•  Customer need to have parameters setting only for one time. DN15-25-W10: DN15-DN25 for 1-10 meters in series.
•  Adopt laser testing head from Japanese SUNX and numerical laser sensor amplifier. Laser testing head has virtues of small optical spot (0.2mm), long verification distance (reach 500mm). Numerical laser sensor amplifier can respond very rapidly ( Maximum speed: 80 microsecond, that is, 12.5KHz/s)
•  It has focusing instructed function.
•  Adopt TCS Series Electronic Balance from Ningbo Keli Company which is one of largest electronic scale sensors manufacturer companies in China. The scale has virtues of high precision, high stability, easy operation, convenient information collection etc.
•  It has instantaneous flow adjusting function. It has automatic abrasion test function of ten thousand times (interrupting test, or to say fatigue test). (No need to purchase ten thousand times wear tester specially). It has the functions of automatic monitoring, display of pressure and water temperature in pipeline.
•  It can have verification repeatedly, and you needn't reset the parameters. It can print various reports respectively. It can have pressure verification for water meter. All the information about the tested water meter will be collected, calculated, displayed and transmitted by independent optical collector and adjustable optical sensor.
•  The equipment has water circulated function, and has virtues of low noise, high stability. It can adapt to all kinds of mechanical water meters verification, and is very flexible.
•  The equipment is made of 304 stainless steel and copper. Sufficient spares for wearing parts are (like o washer etc).
•  Low fault rate, convenient repair. With full technical documents.
•  Flying start and stop
•  Standing start and stop
•  Digital cameras installed on the frame holder above the testing line (optional)
•  High-quality, stainless steel parts (AISI 304, 316, 316I)
