WATER PRESSURE SENSOR AND WATER PIPE PRESSURE MEASUREMENT
Water 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 pressure sensor for water is generally placed in a position such as:
the water input side of the pump.

Pump output side

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

An important part of digital differential 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 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 sensor.

Differential pressures show the difference between inlet and outlet close to the pump, 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
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 sensor. Some water pressure sensors 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 Pressure Sensor for Sewage Treatment Works?

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 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)

Fourth Treatment Stage

Pressure Sensor for Sewage Treatment: Sewage Treatment Steps?

The sewage treatment procedure includes the following step;

: pressure sensor for sewage treatment

Methods to treat sewage:

The four common methods to treat sewage are:

Physical Water Treatment

Biological Water Treatment

Chemical treatment

Sludge Treatment

Technologies Used to Neutralize Water?

The modern manufacturing process relies partially on water. On the elementary level, water is essential to turn raw materials into basic manufacturing resources. Furthermore, water is also required to clean, combine and transform them into daily life products.
During the process, water becomes wastewater due to its exposure to contaminants so it has to go through other rigorous treatments before you release it into natural reservoirs.
Moreover, most of the Industrial factories are now doing on-site treatment of wastewater to cut the costs, and to recycle it back to the manufacturing process.

Moreover, the wastewater cleaning process is based on multiple steps. This process cleanses water from harmful bacteria, chemicals, organic and inorganic compounds of water.
Following are the technologies used to neutralize water and to remove impurities from water;

Reverse Osmosis System

Ultrafiltration System

Vacuum Evaporators

Vacuum Filters

Paper bed Filters

Solid Bowl Centrifuges

Tramp Oil Separators

Types of Instruments Used for Sewage Treatment:

To treat waste water the Industrial manufacturers used the 4 types of basic instruments;

Level Instruments

Flow Instruments

Water Quality Monitoring Instruments

Pressure Instruments

Level Instruments:
We use level instruments to maintain liquid and gas levels in pipes, tanks or silos in wastewater treatment systems.

Usually, treatment pipes are difficult to access because they are opaque so the system operators depend on level radar, sensors, and transducers to monitor the level of water.
In addition, switches are normally connected with the alarms, pumps, or controllers to adjust the incoming flow of water and gas.

Flow Instrument:
Flow instruments are used for two main purposes:

To determine the amount of gas or liquid present in the pipe.

To check the rate at which the gas or liquid is moving through the vessel.

The flow instruments are installed inside the treatment pipes. They measure the volume and mass of gas or liquid at consistent time intervals.

The flowing instrument might be;

Variable area meter

Mechanical flowmeters

Magnetic flowmeters

Thermal flowmeters

And, pressure-based meters.

Pressure Instruments:
Pressure Instruments include;

Transmitters

Sensors

Transducers

Gauges

It is possible to install pressure instruments on the inside of the waste treatment pipes, pumps, and reservoirs.

In addition, these pressure instruments help industries to maintain safe pressure levels and also prevent equipment failure.

Water Quality Monitoring Instruments
These instruments are integral for industrial wastewater treatment. Water also needs to pass the national and local cleanliness standards to be released in the sanitary sewers.

To measure the treatment process, you need to install the water quality instruments inline. The type of meter required per phase depends on the testing environment.

The system in question is also a matter of concern in this regard.

Use of Pressure Sensor for sewage treatment:
We use pressure sensors for measuring the pressure of gas or liquid and variables such as the flow of liquid or gas, speed, water level, and elevation.

A pressure sensor is an electronic device. We also use it to detect, regulate, and monitor pressure. In addition, it converts pressure into an analog electrical signal.

Moreover, the pressure sensor converts the perceived data into an electronic signal.

Technologies used by Pressure Sensor for Sewage treatment.
There are 6 major technologies used by pressure sensors for sewage treatment:

Potentiometric pressure sensors

Inductive pressure sensors

Capacitive pressure sensors

Piezoelectric pressure sensors

Strain gauge pressure sensors

Variable Reluctance pressure sensors
Piezoelectric Pressure Sensors:
These sensors rely on the ability of the materials. Also, their purpose is to generate an electrical potential when you subject the material to mechanical stress. We call this process the piezoelectric effect.

Pressure sensors are of four types;

Aneroid Barometer Sensors

Manometer Sensors

Bourdon Tube Pressure Sensors

Vacuum Pressure Sensors
Water pressure sensors, or water pressure transducers produced by LEFOO company, are used in residential, commercial clean water distribution utilities for water elevated piping pressure measurement. The inlet and outlet water Pipe pressure measurement in water treatment facilities and water purify industries is very important, in the wastewater treatment industry, the measurement of water flow is also vital. Water pressure transducer is also applied in irrigation systems. LEFOO produces various pressure sensors and transducers with excellent accuracy and long-term stability. There is some basic information in this content to review before making a decision on the type of pressure sensor is required.
