Water Column Pressure Sensor

This is done with a simple equation.

Water column pressure sensor. 1 inch of w c. Ast submersible pressure sensor 0 208 inchs water column. Inh2o inches of water. By measuring liquid density liquid height can be accurately measured.

Submersible pressure transducers work just like other pressure transducers except they re inside a water tight housing and they read in feet or inches of liquid adjusted to specific gravity rather than psi. Pressure sensors are therefore particularly suitable in applications of free standing tanks and vessels. Psi is converted to feet by multiplying it by 2 31 and then dividing it by the specific gravity. 27 68 inches of water column 1 psi 420 inches 27 68 inches of water column x density of 1 15 17 psi here the height of the tank is converted into a measurement range.

It is typically used for a differential pressure. 8 inches wc 0 03613 0 289 psi. Water column that is the hydrostatic pressure p at the bottom of the vessel is equal to that of an 8 inch water column. Since the pressure exerted by one metre of water is dependent on its density and the local gravity it is not a fundamental unit of measure for pressure but a derived one which is called a manometric unit.

Since the pressure cannot exceed the height of the tank while considering the density of the liquid the user can measure the maximum amount of signal for the specified range. The sensors reach measurement ranges as low as 0 05 inches of water column approximately 0 0018 psi and their capacitive technology also allows extremely low impact from device age and environmental conditions when compared to competitive units. For vented tank applications the transducer is vented to atmosphere through a tube extending from inside the housing cable end. P 1 8 inches 8 inches w c.

0 03613 psi 27 678 inches of w c. Low range wet wet dp sensor for measuring differential pressure of a liquid from 0 to 4 inches of water column. Meters of water gauge or column is a metric unit for measuring liquid level. The hydrostatic pressure generated by a certain liquid level is typically represented by the equivalent height of a water column.

Pressure at a certain depth within a liquid is directly proportional to the column of liquid above it measured as water column or wc. Wika model s 11 measures the height dependent weight force of the liquid column also known as hydrostatic pressure. This version of the dpt 200 differential pressure sensor has stainless steel fkm elastomer seal components exposed to the measurement media making it suitable for use on liquids compatible with those materials.
