Digital Drinking Water pressure sensors are frequently used for inlet and outlet water pipe pressure measurement in clean water systems at public utilities.

LEFOO WATER PRESSURE SENSOR AND WATER PIPE PRESSURE MEASUREMENT

Water pipe pressure sensors are frequently used for inlet and outlet water pipe pressure measurement in clean water systems at public utilities. Some water systems are fed by the gravity flow of the water, usually, lift stations pump the water to a higher elevation to provide reliable gravity flow. Water pressure in the pump well, water tower needs to be monitored by a water differential pressure sensor to control the predetermined water flow rate at the pump input, which turns off the pump at a minimum flow rate to prevent empty run damage. Also, pump well and water tower that undergoes a large release of water require water supplement. Pressure sensors for water pumps offer reliable pressure measurement for the pump and the observer can determine when to adjust additional pressure and flow by the measured values.

A drinking water pressure sensor is generally placed in a position such as:

The water input side of the drinking water pressure sensor

Pump output side

Clean end location (pump wet well, elevated pipe...)

In Lefoo, pressure transmitter manufacturer, there is an important part of digital water pressure sensor selection is ensuring that any electronic transducer transmitter used is compatible with potable water. Pressure transducers are responsible for monitoring the pressure, at various locations throughout clean water systems and often interface with pumps to show, when increased pressure or flow rates are necessary.

HOW TO SELECT A DRINKING WATER PRESSURE TRANSDUCER

Water pressure transducers can measure pressure in several different ways:

1. Absolute pressure VS gauge pressure vs Differential pressures

Absolute water pressure is measured against vacuum or pressure-free.

Gauge pressure measures water pressure under atmospheric pressure. A vent tube is used to allow air to enter the sensor. The vent line can often be run through the power cable supplying the drinking water pressure sensors.

Differential pressures show the difference between inlet and outlet close to the pump with hvac differential pressure sensor, or in two water towers, or two water pipes. You can use differential pressure sensor to measure pressure drops across filters or measure flow rates by measuring the difference in pressure across a restriction.

2. Technology of water pipe pressure sensor

In Lefoo, Water pressure sensors or transducers apply an oil-extended silicon unit, the unit contains a crystal chip made of diffused silicon, which bends as pressure is applied and generates electrical power. There is a diaphragm close to strain Wheatstone Bridge, which changes its resistance on 4 lines when force is in contact. This Wheatstone Bridge is used to modify the output voltage of the drinking water pressure sensors. Some pressure sensor for water pump provide zero-based outputs, the zero pressure occurs when no actual flow happens. When water flows through the sensor it will generate voltage signals.

HOW DOES DIGITAL WATER PRESSURE SENSOR WORKS FOR SEWAGE TREATMENT?

The sewage water is the wastewater used by the community. It is black or grey water and has a foul smell. In order to clean the wastewater from contaminants, we perform the sewage treatment using a water pipe Pressure Sensor for Sewage Treatment.

Therefore, to remove these contaminants, different chemical processes take place. The three process steps of Sewage treatment are:

Primary Treatment (temporary holds the sewage, the settled and floating particles are removed and then released for secondary treatment)

Secondary Treatment (to remove dissolved and suspended biological matter)

Tertiary Treatment (final cleansing process)
