Pressure transmitters help lift stations monitor the collection and control the flow of water, wastewater, and often storm water in the water supply and wastewater treatment industry.

Lift stations pump collected water to higher elevations to take advantage of gravity helping to transport the water. They’re often used in conjunction with canals, levees, and locks to control storm water in low lying municipalities where flooding potential exists. 

The following industries take advantage of the power of lift stations:

  • Industrial Water Treatment
  • Municipal Water Management and Treatment
  • Mining Applications

Parts of a Lift Station

As seen in Figure 1, lift stations are typically composed of a concrete storage tank, submersible pumps, liquid level sensors, and control systems. Submersible pumps at the bottom of lift station storage tanks are able to pump suspended solids, sewage, and refuse. Pressure transmitters are often used to check for blockages and flooding and can also be used in pump staging to:

  • turn on additional pumps during flooding
  • equalize wear on pumps
  • turn pumps off when the tank is low.

The WIKA LS-10 and Its Features

The nature of wastewater, storm water, sewage, and refuse pumped through lift stations requires that the equipment be compatible with moderately harsh and corrosive media. Therefore, pressure transmitters used in the equipment must also be compatible with moderately corrosive media and bio-waste.

The WIKA LS-10 electronic pressure transmitter with the Levelguard attachment, as shown to the right, has been designed for reliability in water supply and wastewater treatment applications like lift station monitoring.

When selecting a pressure transmitter, consider the following:

  1. Absolute or gauge pressure measurement
  2. Anti-clog protection with WIKA LevelGuard™
  3. Cable or flying lead pressure transmitter wiring
  4. Conduit or non-conduit pressure transmitter protection
  5. Constrained or unconstrained submersible pressure transmitters
  6. Liquid level and liquid volume measurement in non-linear tanks
  7. Media compatibility for pressure transmitters
  8. Moisture resistance in pressure transmitters
  9. Pressure transmitter accuracy and errors
  10. Pressure transmitter cable lift systems
  11. Standard or flush diaphragm pressure transmitters
  12. Submersible or tank wall mounted pressure transmitter
  13. Vent filtration and protection of gauge reference pressure transmitters
