Description Technical Specs Suggested Applications   These flow/pressure meters are designed using Venturi theory and MEMS (Micro Electro-Mechanical Systems) technology.  A Venturi tube is a common apparatus for measuring flow. It is a tubular construction generally made of heavy, expensive casting.  A fluid passing through smoothly varying constrictions is subject to changes in velocity and pressure in order to satisfy the conservation of mass-flux/flow rate.  (Bernoulli's Principle) The reduction in pressure in the constriction can be understood by conservation of energy : the fluid (or gas) gains kinetic energy as it enters the constriction, and that energy is supplied by a pressure gradient of force from behind. The pressure gradient reduces the pressure in the constriction, in reaction to the acceleration. Likewise, as the fluid leaves the constriction, it is slowed by a pressure gradient force that raises the pressure back to the ambient level.  These measurements are then sensed using MEMS technology to produce highly accurate readings of flow, accumulated flow, and pressure.   Features Low Cost Easy Installation No Technical Personnel Required to Perform Calibration Quick Response Large Easy to Read Backlit LCD Display Measures fluid flow in LPM & GPM, pressure in Kg/cm2 or PSI, and total flow volume in Liters or Gallons Pressure, Flow Rate, and Total Flow Displayed Simultaneously Total Accumulated Flow Reset and Pressure Zero Offset Combo Function for flow/pressure meter and signal output
