General information

First, it is our exclusive product.

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. It has integrated output of flow rate, temperature and pressure. It is suitable for measuring many kinds of mediums. It is widely used as energy-efficient equipment.
