LZP intelligent differential pressure (Equilibrium) flow meter is a great improvement based on the conventional standard orifice-plate flow meter that has only one flow passage. With more flow passages on the flow sensor, LZP flow meter ensures irregular fluid can be changed into ideal state when it passes the flow sensor, and ensures double functions of throttling or pressure tapping and reshaping standard flow field, which is a revolutionary advance for the conventional fluid measurement technology. It can be a replacement for many differential pressure flow meters (e.g. standard orifice-plate, V cone, venturi tube, velocity-averaging tube, wedge, elbow), applicable for measuring multi fluids. Compared with standard orifice-plate flow meter, LZP intelligent differential pressure (Equilibrium) flow meter can provide more accurate measurement by 5-10 times, 1/15 of flowing noise, 1/3 of permanent pressure loss, twice faster pressure recovery, and can correct and offset parameters by its pressure and temperature sensors according to constant changes of surrounding pressure and temperature, reaching real flow rate. This flow meter has the straight pipes whose minimal diameter can be less than 0.5D with no movable parts, making it easy as standard orifice-plate flow meter in installation and usage, saving large amount of straight pipes and energy consumption for fluid movement. Integrated output of flow rate, temperature and pressure. It is suitable for measuring many kinds of mediums.It will be widely used as energy-efficient equipment.

 

Standard throttling device legenerate a large number of eddy current and energy losses:

 

LZP intelligent differential pressure (Equilibrium) flow meter balance the flow field, reduce eddy current and energy losses:

 

Standard flow meter require a very long straight sections to balance the flowing medium,

the LZP intelligent differential pressure (Equilibrium) flow meter saves a huge amount of straight sections to cut the equipment cost:

 

LZP intelligent differential pressure (Equilibrium) flow meter is a high accuracy measuring equipment, the accuracy is between 0.3%~1.0% (depends on the bore of the equipment). It also has wide measure ratio. There is no top limit when reynolds number is greater than 50,000 (Working under correct bore parameter. Normal measuring ration is 10:1. When chose correct bore parameter, measuring ration can increase to 30:1, 50:1 or more.

 

It is able to balance the flow field as well as measuring flowing rate, it increase the repeatability up to 0.1%. Balanced flow field decrease friction between throttling parts and fluid medium, reduce attrition, keeping β value stable. There is no movable parts on entire equipment, therefore, it will maintain the stability for a long-term, increase equipment life 5~10 times than the standard throttling device. Balanced design of porous symmetry will reduce eddy current, in order to keep clean of every hole, minimise the chance of equipment block. It has a wide measuring ratio. According to testing result, the flowing speed of medium can start from minimum to speed of sound; and the minimum reynolds number can less than 200, and maximum reynolds number can be 10⁷. β value range: 0.25~0.9.

 

It's working temprature and pressure depends on the matirail and level of the pipeline and flange. The maximum working temprature can be 850°C or more, working pressure can reach up to 42MPa.
