High-pressure angle type water meter quality method calibrating device

Abstract

The invention discloses a high-pressure angle type water meter quality method calibrating device which comprises a water tank, a pressure stabilizing container, a commutator, a meter detecting table and a standard measuring vessel, a water pump is arranged on a water pipeline between the water tank and the pressure stabilizing container, the outlet end of the pressure stabilizing container is communicated with the meter detecting table through a gettering filter and a process pipeline, and the outlet side of the meter detecting table is connected with the commutator through the standard measuring vessel; the standard measuring vessel arranged on the outlet side of the commutator adopts an electronic scale, and a weighing container is arranged on the electronic scale; a plurality of meter detection stations are arranged on the meter detection table; the meter checking stations comprise multi-caliber meter checking loops which are connected in parallel, each meter checking loop is provided with a plurality of groups of meter checking stations which are connected in series, and switching valves are arranged on pipelines on the water inlet side and the water outlet side of each group of meter checking stations. A static mass method and a standard meter method are combined, and the defect that a high-pressure water meter calibrating device is single in calibration in a volumetric method is overcome; a static mass method verification system can be used for calibrating and tracing a standard flow meter used in the device at any time, and accurate and reliable quantity value transmission is better guaranteed.

Description

technical field [0001] The invention relates to water meter verification equipment, in particular to a high pressure angle type water meter quality method verification device. Background technique [0002] The high pressure angle water meter refers to the angle structure high pressure water injection meter with the maximum working pressure exceeding 1.0MPa, mainly used for underground high pressure water injection in oil field production, polymer injection in oil layer and other industrial water metering instruments. With the development of measurement technology, more and more high-pressure water meters are developing towards the trend of automation, high efficiency and integration. On the one hand, it is to adapt to more and more measurement and testing services; performance of participation. Therefore, how to ensure the accuracy of the flow measurement of the high-pressure water meter is particularly important. [0003] Water meter verification device is a necessary sta...
