Why Choosing Us?
Compared to other flow meters, mass flow meters are the best choices to handle the problems like High/low temperature, high pressure, high viscosity, micro flow, large temperature and pressure fluctuations, rapid response, and accuracy, etc. Mass flow meters can be used as density meters and they are regarded as the 21th century flow meter.
Beijing Sincerity Automatic Equipment Co,. Ltd is a professional manufacturing factory particularly producing mass flow meters. Our company was reformed from the China Petroleum &Chemical Corporation's Beijing Research Institute of Chemical Industries in 2006. Mass flow meters are star products here.
Our company has strong technology skills and is capable of designing, installing, adjusting and making comprehensive analyses to the problems in manufacturing process. We will offer you the best measuring solution. We have particular professional formula to produce the measuring pipeline compared to the other producing factories. Zeropoint Stability is good. Medium with tiny flow rate could be measured precisely, which reaches a minimum of 0- 1kg/h. Gas with either low pressure or with high pressure could be measured as well. Give us your problems, and you will never be disappointed!
We are not only the expert of fluid measurement, but also the expert of automatic control. We will provide the most effective solutions to the enterprises that have the measure requirement by using optimum allocation, perfect function, simple operation, thoughtful service and strong support. Hope that Beijing Sincerity Automatic Equipment Co,. Ltd will become the new flagship in the international flow measurement industry!

Installation requirements:
A. Requirements to installation environment:
1.The flow meter and its cable shall not be installed near the equipments with fairly great electromagnetic disturbance, the flow meter shall be over 1m away from motor and large scale relay, etc.,
2.The flow meter must be over 3m away from the strong vibration source equipments as motor, pump, vibrator and bumper jar, otherwise it must be taken by separation bracing measures, or taken by special measures as adding the metal hose between the connected vibration sources.
3.The power line of the transducer shall be separated from that of the main power consumers.
As to outdoor installation, it shall take into account the wind-proof and rain-proof measures to avoid disturbance in wind and rain, and improve the service life of flow meter.
B. Installation operation requirements:
1,The lower reaches pipe of the flow meter shall have certain back pressure, at the flow meter inlet and outlet, the regulation valve is mounted. Regulate the flow through regulating the regulation valve at the outlet, and it shall not be directly in the open status, during measurement of flow meter, it shall ensure the measuring section of the flow meter full of fluid, otherwise it shall incur very serious deviation and the error of measurement.
2,In the actual application, the flow meter would not be in contact with the other objects, the upper and lower parts of the transducer encasing shall not be stocked by foreign substances, and it is not allowed to use the transducer encasing as the pipe support, and it must be away from the ground.
3,The upper reaches pipe diameter of the flow meter must be equivalent to or over the flow meter size.
124.The flow meter may be directly mounted on the pipe, nevertheless the pipe openings at two sides of the flow meter, or the position of 6-10 folds pipe diameters on the flange, must be added by bracing with sufficient strength, rigidity and mass. The bracing and pipeline shall be fixed by fastener to minimize the impact of pipeline vibration to flow meter.
5. During installation, the pipe shall be aligned to enable the coaxial between the flow meter and pipe either in axial or radial direction, the forcible position alignment is not allowed, so as to avoid the torque or bending moment on the primary instrument; it shall strive to implement zero stress installation. In the strong vibration environment, the expansion joint shall be used to eliminate the impact of vibration to flow meter. The flow meter installation shall adopt the proper means as the case may be (refer to chart below)
6. When flow meter is used for batch filling, the flow meter shall be in parallel connected to the bypass (see typical installation chart), and this shall also be in favor of maintenance.
