What Is Static Water Pressure?
Definition of Static Water Pressure: Static Water Pressure refers to the pressure on water when it is stationary or moving in a straight line at a constant speed. Static Water Pressure is also called hydrostatic pressure. In fluid dynamics, many authors use the term static pressure, not just pressure, to avoid ambiguity. In general, however, the word “static” can be discarded, and the pressure in use is the same as the static pressure at a given point in the fluid.
How to Calculate static water pressure?
Static Water Pressure Formula
Static Water Pressure or Hydrostatic pressure in a liquid can be calculated as:
p = ρ*g*h
p = pressure in liquid (N/m2, Pa, lbf/ft2, psf)
ρ = density of liquid (kg/m3, slugs/ft3)
g = acceleration of gravity (9.81 m/s2, 32.17405 ft/s2)
h = height of fluid column – or depth in the fluid where pressure is measured (m, ft)

Static Water Pressure Gauge
In the process of industrial process control and technical measurement, because the elastic sensitive element of the mechanical water pressure gauge (Static Water Pressure Gauge) has the characteristics of high mechanical strength and convenient production, the mechanical water pressure gauge is widely used.
The elastic sensing element in the Static Water Pressure Gauge elastically deforms as the pressure changes. Static Water Pressure Gauge adopts spring tube (Bourdon tube), diaphragm, diaphragm, bellows and other sensitive components and is classified according to this. The measured pressure is generally regarded as relative pressure. Generally, the relative point is selected as atmospheric pressure.
The elastic deformation of the elastic element under the action of medium pressure is amplified by the gear transmission mechanism of the water pressure gauge. The water pressure gauge will display the relative value (high or low) relative to the atmospheric pressure.
The pressure value within the measurement range is displayed by the pointer. The indication range of the dial is generally 270 degrees.
It can be divided into precision water pressure gauge and general water pressure gauge. The measurement accuracy levels of precision water pressure gauges are 0.1, 0.16, 0.25, 0.4 and 0.05 respectively. The measurement accuracy levels of general water pressure gauges are 1.0, 1.6, 2.5 and 4.0 respectively.

Water Pressure Is Measured by Which Instrument
In industry, there are multiple instrument options for measuring the static pressure of water.
For example. If you need to measure the water pressure on the pipeline, you can choose a water pressure gauge or a pressure transmitter.
If you need to measure the water pressure in the tank, you can use a diaphragm pressure or differential pressure transmitter.
If Need to measure the pressure of downhole water, you can use a submersible level sensor. The latter two are also commonly used for water level measurement.
