Balanced Flow Meter

The multi-pore rectifying type throttling device integrates the properties of standard pore plate with flowing conditioner to form to be an energy conservation environment-friendly flow meter sensor. The balanced flow meter sensor is provided with multiple function holes which can extremely balance and rectify the vortex into the fluid similar to ideal fluid; the balanced flow meter sensor is specifically applied to the flow meter measuring condition with short straight pipe section, high precision requirement, and complex work condition. And the balanced flow meter has been widely applied to the industries such as chemical industry, petroleum, metallurgy, power, natural gas, water process, etc.

Main Characteristic
• Special structure form
The throttling component and the flowing rectifying device are organically combined to form the balance throttling component which is capable of balancing and rectifying the complex flow field and removing vortex and improving flow field in short distance; furthermore, the medium noise can be greatly reduced, thus the measurement signal is more stable resulting in greater measurement precision.
• Requirement of short straight pipe section
By adopting special structure of the balance throttling component, the pressure is restored 2 times quicker than that of traditional throttling device, which greatly reduces the requirement on straight pipe section; in common condition, the straight pipe section is designed as 2D at the front and 2D at the back as required.
• Low permanent pressure loss
The balance throttling component reduces (or removes) vortex by rectifying and balancing the irregular flow of resisting component, as well as accelerates to achieve the process with ideal flow and reduces the length of the necessary straight pipe section; said conditions are benefit for reducing the permanent pressure loss; the permanent pressure loss is about 1/3 of that of the pore plate throttling device based on the same value.
• Improved smudge resistance
The balance throttling component has multi-pore symmetric structure, which greatly reduces the formation of dead area, ensures the smudge medium successfully passing through multiple pores, and reduces the problem that the fluid pore is plugged.
• Wide measurement range application
The full package of the medium such as gas (air, gas, natural gas and the like), steam and liquid (chemical liquid such as water solution) and the flow rate of the bidirectional fluid can be measured; the balance throttling component is suitable for different circular pipes and quadrate pipes. The balance throttling component has unique design, and is made of high strength corrosion resisting material, thus it has high strength; and the balance throttling component is applied to the conditions such as high temperature and high pressure condition, corrosion resistance condition, and anti-explosion dangerous condition.
• High precision and large measurement range
The precision is top to +-0.5%, +-1.0%; the repeatability is +-0.1%; and the measurement range is more than 10:1
