S.H.Meters
Overview
Liquid flow standard devices are widely used in the experimental and verification devices of liquid flow meters, especially for flow meter manufacturers, where there are a large number of meter verification and product development experiments, and a set of efficient and reliable liquid flow standard devices are produced for them. Activities are of great significance. In industrial applications, the flow standard device must not only have sufficient accuracy and reliability, but also have a relatively high verification efficiency. Factors such as the construction cost of the device, the operating cost, and the technical requirements of the operators must also be considered. Traditional liquid flow standard devices are mostly based on mass method and volume method. The flow source depends on the pump to provide flow, but the flow is pulsating, the flow stability is poor, and the flow point adjustment is not accurate. However, with the flow measurement and testing technology With the rapid development of these devices, these devices have not been able to meet the requirements well. In order to meet the requirements of liquid flowmeter verification, calibration, factory inspection and the growing trend of new flowmeter production, our company designed and manufactured an active piston liquid flow standard device using water as the medium. This standard device is unique in design and its basic working principle It compares the volume flow of the fluid discharged by the piston with the volume flow of the tested flowmeter in a certain time interval. The volume of the fluid discharged by the piston is obtained by the product of the cross-sectional area of the piston cylinder and the displacement of the piston. Driven by the servo motor, it reduces the disturbance to the liquid flow. It has many advantages such as stability and reliability, good repeatability, high degree of automation, and simple operation. It avoids the shortcomings of the start-stop effect or the commutator effect of the traditional liquid flow standard device. Conducive to improving the level of measurement uncertainty. The device also has the characteristics of self-contained, compact structure, high efficiency and energy saving, no need to build a pool, no need to put forward special structural requirements for the building, and is very suitable for production testing and product development testing of small flow meters.
Device composition
This device is composed of water source system, clamp meter pipeline, flow adjustment device, standard device system, and software control system.
Flow regulation control
The device is equipped with two flow point pipelines, and two electromagnetic flowmeters are used as flow indicating devices. The electromagnetic display of DN2.5 diameter is used below 250L, and the electromagnetic display of DN25 is used above 250L. It is equipped with three flow point pipelines, which are respectively used to adjust Q3\Q2\ Q1 flow point.
You need a good solution for water metering---Catering all your needs.
As the China’s professional manufacturer and distributor since 2013, we have developed a comprehensive water meter range and a complete solution for the Commercial ,agriculture, Industrial and Domestic market on Mechanical type water meter and smart water meters. Moving with the changes in technology and precision metering has been the mission of the company since its genesis and we are adding metering that can support water sustainability using. Since 2017, we start the export smart water meters to the whole world, and hope more and more countries and region people can save the water with us together with the smart technology and system. Nowadays, S.H.Meters have already become one the main important exporter for water flow meters in China.
We will provide your product to your hand in timely manner and keep you informed of process with your order throughout the whole sales. From the strictly QC inspection, strictly cost control and five star quality services, we believe that you will own a more solution on water metering.
