| Product Description |
1, purpose of requirements
To ensure the speed of water meter (water flow meter) to test the stability of flow field, pressure, water meter international standard ISO4064 compliance with the relevant provisions of the "high water tank or container equivalent of high water tank regulator, variable frequency pump source such as" requirements, special configuration Regulators container.
2, the structural principle
Structure as shown, water (water flow meter) to test the unit's regulator is equipped with pressure vessel or container is different from the transition container, but according to the design and manufacture of special purpose requirements, the structure has a certain degree of particularity, according to traffic the size of the high and low pressure, load one or more; on regulator size of the container, import and export path, position, flow, spacing, arrangement, separator layers, pore size and the number of holes are luxurious. The role of regulated containers principle is to pump the main source of multi-stage damping to reduce expenditure, subject to dynamic pressure changes in static pressure (equivalent to high overflow tank), according to a certain percentage of liquid gas volume flow pump pulse wave absorption to ensure that each point of a test flow test flow is stable and reliable process. See "water meter and its test," a book.

5, features and application examples of our products
Our design of the regulator is the reference to domestic and foreign container specifications, and further testing of the Zhejiang Institute of Technical Supervision, "the container of water flow device regulator method" scientific research (83 provinces and the State Bureau of Science and Technology Year Third Prize) transformation and application. The project has accumulated years of experience has formed a complete series of products, compact, effective regulation, not only for water meter installations in various types of water flow can meet the matching standard device requests. This is also a major feature of our products.
Shenzhen, a unit is equipped with eight pressure vessels in series parallel, multi-stage regulator reported by the on-site assessment, which 8 the role of the container no help regulators, water test indication error is almost always become
