Where Water Pressure Comes From, There Accurate Measurement Matters

Whether in a municipal water system, industrial water treatment plant, groundwater monitoring, or agricultural irrigation system, pressure guarantees a steady flow of water to its intended destinations. However, too high or too low water pressure can cause problems like leaks, burst pipes, or inadequate water supply. Therefore, water pressure within every water system must be carefully monitored and effectively managed. Here, the water pressure instruments work for constant and real-time monitoring of water pressure within safe and efficient parameters.

What's the Source of Water Pressure?

Water pressure is the force exerted by water per unit area within a given system, such as pipes or containers. The aim is to ensure water reaches all parts of the distribution system at the desired pressure levels. It primarily comes from gravity or mechanical devices like pumps.

• Gravitational Potential Energy: Water stored in a reservoir, tower, or elevated tanks gains pressure due to gravity. Water pressure comes from the height difference between the water source and the distribution points. The higher the height, the greater the potential energy, and thus the pressure at the point of withdrawal. For example, a water tower positioned at a high elevation provides natural pressure to the system.

• Water Pumping Systems: Pumps are used to actively increase water pressure in municipal, industrial, or residential water systems. Pumps add energy to the water, pushing it through pipelines to various locations even when elevation differences are minimal. Most modern water systems rely on water pumps to generate pressure, balancing the flow rates and adjusting pump operation dynamically. Pump pressure can be adjusted depending on the system requirements.

Where are Water Pressure Instruments Installed?

Where water pressure comes from, there the pressure instruments are. To effectively monitor and maintain optimal water pressure, pressure measurement instruments need to be installed at strategic locations:

For Water Towers/Tanks/Containers

• Inside (At the Bottom or Side Wall): A water pressure transmitter or water level transmitter directly measures hydrostatic pressure. It indicates the real-time volume of water, ensuring an adequate water supply and preventing overflow.

• Outlet Pipeline: Placed and integrated with the pipeline to monitor pressure, which can aid in system balancing, troubleshooting, and consistent water distribution.

For Pumps

• Suction Side(Inlet): A water pressure transmitter is installed directly on the pipe before the pump inlet. Monitor inlet pressure to prevent cavitation and ensure adequate supply pressure.

• Discharge Side(Outlet): Monitor discharge pressure to verify pump performance, control pump operation, or for pressure control systems.

Water Pressure Gauge or Water Pressure Transmitter?

Choosing a suitable pressure instrument between a pressure gauge and a pressure transmitter depends on your specific needs. But generally, pressure transmitters are considered superior for most modern water systems.
