Water supply systems often struggle to maintain steady pressure when demand changes. This can cause discomfort, waste energy, and wear out equipment faster. ProSense Constant Pressure Water Supply offers a solution by keeping water pressure stable through smart pump control. This system adjusts pump speed in real time based on actual water use, ensuring consistent pressure, saving energy, and protecting the entire water network.
How ProSense Constant Pressure Systems Work
At the heart of the ProSense system is a pressure sensor that continuously monitors water pressure. This sensor sends a signal, either 0–10V or 4–20mA, to an inverter. The inverter uses a built-in PID (Proportional-Integral-Derivative) controller to compare the actual pressure with a preset target pressure.
When the pressure falls below the setpoint, the inverter increases the pump speed to raise pressure. When pressure is above the target, the pump slows down. This automatic adjustment keeps water pressure steady regardless of how many taps or appliances are running.
During times of low water use, the system enters a sleep mode to save energy. The pump stops running but wakes up immediately when pressure drops again, ensuring water is always available without wasting power.
Key Advantages of Using ProSense Systems
ProSense constant pressure systems bring several benefits that improve water supply performance and reduce costs:
Stable water pressure thanks to automatic PID control, which adjusts pump speed smoothly and precisely.
Energy savings through the sleep/wake function that reduces pump operation during low demand.
Protection of pipes and fittings by preventing water hammer and overpressure, common problems in traditional systems.
Space-saving design since no water tank is needed, reducing installation footprint and avoiding tank-related contamination risks.
Longer pump life due to smooth motor starts and fewer pressure fluctuations, lowering maintenance needs.
These advantages make ProSense systems ideal for residential buildings, commercial facilities, and industrial sites where water demand varies throughout the day.
Setting Up Core Parameters for Optimal Performance
Proper configuration is essential to get the best results from the ProSense system. Key parameters include:
P0-02 = 1: Enables external start control.
P0-03 = 8: Sets PID frequency control mode.
PA-01: Defines the target pressure as a percentage of maximum.
PA-02 = 0: Selects AI1 as the feedback input.
P8-49: Sets the pressure point at which the system wakes up from sleep mode.
P8-51: Defines the frequency during sleep mode.
Adjusting these settings according to the specific pump and water network ensures smooth operation and reliable pressure control.
Important Tips for Installation and Operation
To avoid common issues and maximise system efficiency, keep these points in mind:
Choose the correct sensor input type (0–10V or 4–20mA) based on your sensor model.
Double-check wiring connections and confirm the motor rotates in the correct direction.
Set the PID control direction properly to avoid unstable pressure.
Avoid enabling sleep mode during periods of high water use to prevent pressure drops.
Position the pressure sensor away from pump outlets or air tanks to prevent pressure oscillations.
Following these guidelines helps maintain stable pressure and extends the life of your water supply equipment.
Practical Example of ProSense System Benefits
Consider a mid-sized apartment building where water demand peaks in the morning and evening but drops during the day. A traditional pump runs at full speed regardless of demand, causing pressure spikes and wasting energy.
With ProSense constant pressure control, the pump speed adjusts automatically. During peak times, the pump runs faster to maintain pressure. During low use, the pump slows or sleeps, saving energy and reducing noise. Residents enjoy consistent water pressure for showers, dishwashers, and washing machines without sudden drops or surges.
Maintenance teams report fewer pipe bursts and longer pump life, lowering repair costs. The building also saves on electricity bills thanks to reduced pump run time.
Summary
ProSense Constant Pressure Water Supply systems offer a simple, efficient, and reliable way to maintain stable water pressure. By automatically adjusting pump speed based on real-time demand, these systems improve comfort, save energy, and protect equipment. Proper setup and installation ensure smooth operation and long-term benefits.
