Pressures from 2 PSI up to 50 PSI
Wastewater lift stations, or pumping stations, are an integral part in the transportation and eventual treatment of wastewater and other used water. Wastewater is commonly transported through piping systems, using gravity to move the water from one location to another. Using gravity helps keep costs down during transportation. However, gravity cannot be used when the wastewater needs to be transported to a higher elevation. This is where lift stations come in.
There are three main components of a lift station:
- Wet well – This is a single tank, located underground, where the wastewater is held until it is ready to be pumped (or lifted) to the higher elevation piping system.
- Submersible pump – A submersible pump is lowered to the bottom of the wet well. Its job is to pump the wastewater out of the wet well when required.
- Submersible pressure transducer – A submersible pressure transducer is also lowered to the bottom of the wet well and connected to a control system at the top of the well. Its job is to continuously monitor the level of the wastewater in the well. Users are able to pre-set, via the control system, the max allowable level in the well before automatically turning the pump on and emptying. The pressure transducer will continue to monitor during the pumping process and the pump will automatically turn off when the pressure transducer indicates that the level has reached the pre-set low level.
CS15 Non-Clogging Submersible Pressure Transducer
Core Sensors offers the CS15 Non-Clogging Submersible Pressure Transducer, designed specifically to meet the demands of the wastewater industry.
Features include:
Level Control – How It Works
For this example, lets assume that the CS15 Non-Clogging Submersible Pressure Transducer installed has a 0-10 PSI calibrated pressure range and a 4-20mA output signal. The installer of this lift station wants the wastewater level to never get higher than 9 PSI (or ~20.75 feet of water) and no lower than 3.5 PSI (or ~8 feet of water). The installer would set up the control system of the lift station with these desired set points. With these parameters set, the CS15 pressure transducer would operate as follows.
- The CS15 submersible pressure transducer will continuously monitor the level in the wet well and transmit the linear output signal to the control panel.
- When the sensor measures 9 PSI, or ~18.4mA, the control panel can initiate the submersible pump to turn on and start lifting the wastewater out of the outlet pipe of the wet well and further along the piping system.
- As the sensors pressure measurement drops to 3.5 PSI, or ~9.6mA, the control panel will turn off the submersible pump, ending the pump out procedure.
Versatility
The CS15 can be configured to suit your specific installation.
- Low power output options are available. Core Sensors offers a 0.5-2.5V non-ratiometric output signal that will operate off of an unregulated 3-5VDC power supply. This option is excellent for remote lift station applications. Lift stations are typically continuously monitoring the level in the well so battery life or the viability of solar will need to be considered when selecting this output signal.
- Customers can select the pressure range that is calibrated into the sensor. We offer ranges from 2 PSI up to 50 PSI. Only need 0-20 PSI? No problem! We can custom calibrate just about any pressure range requested.
- While the cable run is commonly short in lift station applications, Core Sensors offers many different cable lengths to choose from. 16 meters is the standard length for the CS15 but longer lengths are available.
