Water Line Pressure

Water line pressure measurement may be useful in estimating flow rates or checking the pressure drop in domestic water systems. Typical water pressure in buildings on a municipal system is about 50 to110 psi. Extremes may be lower and higher. Typical water pressure in buildings on private wells is about 30 to 50 psi.

Application notes

  • Internal parts must be compatible with water. If used in potable domestic water systems, tubing and fittings must be acceptable in potable water systems.
  • Observed water pressure will vary with the elevation of the sensor relative to the point of intended measurement. If possible, mount the transducer at the elevation of the intended measurement. An elevation difference of 1 foot yields a pressure difference of about 0.43 psi, if the connecting tube is filled with water.
