Pressure Transducers and Water Pipe Pressure Measurement

Water pressure transducers also called a water pressure sensor,
are pressure transmitters that can measure water pipe pressure.

For the water level/water depth measurement,
in the tank, or in the well, we can use electrical transmitters,

stainless steel body, IP65-IP6, 4-20ma output.

Sino-Instrument also offers pressure transmitters with 0-5V/0.5-4.5V, just contact us now.

Sino-Instrument applies application expertise to design and manufacture pressure sensors and transducers for the water industry.

Various factors impact the selection and long term use of water pressure sensors and transducers,

in residential, commercial, and irrigation systems.  

Sino manufactures various products with design features,

to offer excellent accuracy and long term stability.

Below is some basic information to review,

before making a decision on the type of pressure sensor technology,

as well as the electrical and mechanical features required.

Water Compatibility

WATER PRESSURE SENSORS
WATER PRESSURE SENSORS

A pressure sensing element will come in contact with varying pH levels,

depending on the type of water, chemicals added,

and the quality of the water purification process.

Sino packages pressure sensors using silicon strain gages,

mounted onto a one-piece, 316L stainless steel sensing element.

316L SS offers excellent media compatibility for residential,

and commercial water applications and is an NSF61 compliant material.

Environment

Rain, ice, dust, and pressure washers can cause water to seep into sensor housings,

and cause the electronics to short.

Sino offers sealed gauge reference pressure sensors to protect the electronics from these conditions.

Electrical Isolation

Improper grounding and lightning strikes can cause electrical failures of pressure sensors,

as a result of isolation failure.

Sino can include custom electronics and a sensing element to withstand 500VDC isolation to work in extreme electrical conditions.  

The use of a 4-20mA output signal for transmission lengths greater than 15 feet in environments with electrical noise,

will help prevent signal loss or noisy signal conditions.

Using Pressure Transducers for Water Pipe Pressure Measurement at Water Distribution Utilities

Inlet and Outlet Water Pipe Pressure Measurement in Clean Water Systems

Clean water systems use lift stations and gravity feed reservoirs,

to pump water between locations.

In some residential settings,

lift stations and water towers alone cannot supply enough pressure,

to provide users at higher elevations with clean water.

Also, water reservoirs and water towers,

that experience sudden, large draws of water need replenishment.

Pressure-controlled variable frequency drive pumps (VFDs) are used with pressure transducers,

for reliable electronic pressure measurement to determine,

when extra pressure and flow are required by users.

Pressure transducers are used to monitor water pressure,

at elevation, in reservoirs, and the rate of change in each.

VFD pumps interpret the pressure inputs,

and output the necessary increase or decrease in pump output pressure and flow rate.

Electronic Pressure Transducer Applications for Water Pipe Pressure Measurement in Clean Water Systems

Pressure transducers are used for inlet and outlet water pipe pressure measurement,

in clean water systems at public utilities.

An electronic pressure transducer is typically used in water distribution applications such as:

  • Pump intake pressure measurement
  • Pump output pressure measurement
  • End location (reservoir, elevated piping, etc.) pressure measurement

An important part of pressure transmitter selection,

is ensuring that any electronic pressure transducer 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 VFD pumps to show,

when increased pressure or flow rates are necessary.

The SI-200 and SI-390 electronic pressure transducers are designed for long lifetimes,

in both inlet and outlet pipes of clean water systems.

They can usually be delivered within days in a wide variety of configurations.

How to select a pressure transmitter for water pressure?

  1. Absolute or gauge pressure measurement
  2. Cable or flying lead pressure transmitter wiring
  3. Media compatibility for pressure transmitters
  4. Moisture resistance in pressure transmitters
  5. Pressure transmitter accuracy and errors
  6. Radiofrequency (RFI) and electromagnetic interference (EMI) in pressure transmitters
  7. Standard or flush diaphragm pressure transmitters
  8. Vibration resistance in pressure transmitters
