Product Specifications
VAG-Armaturen's innovative concept enables it to make an important contribution to the reduction of water loss. The systematic reduction of pressure in the main water supply system enables large amounts of drinking water to be saved.
Method
A plunger valve and a pressure sensor and flowmeter are installed at the supply area's feed point. A programmable logic controller (PLC) records, processes and archives the measured sensor data that are needed to control the plunger valve. Depending on the supply system's topography and consumption, the valve is moved into the position that optimally reduces the supply pressure. Reducing the supply pressure reduces the amount of water lost. Positive sideeffect: Reducing the supply pressure reduces the risk of new leaks occurring in the supply system.
24 x 365 monitoring of the supply system
The feeding volume and supply pressure are constantly monitored and available for your review and analysis. Secure cellular technology is used to transfer the data to a PC that is connected to the internet. A software programme enables you to follow the valve's operation online, making laborious journeys to remote supply points a thing of the past. Failures are sent to the responsible service team in the form of an SMS alert. Your service personnel is only notified when they're needed, saving you time and money. A local control cabinet enables you to monitor the pressure and operate the valves by hand. All of the important operating information can be viewed on a text display. Control parameters can be viewed and changed on site.
System
Our system solution consists of several components. The figure displays a bypass solution that enables a water supply system operator to mechanically override the control device at any time. At the heart of the system is a VAG plunger valve. Based on the type of local power supply in your water system, the valve is powered by a DC, AC, or three-phase actuator. A flowmeter continuously records the actual volume of water that is supplied to the distribution area. The pressure sensor behind the by-pass is used as actual value for the pressure reduction function of the PLC. Status information about the volume taken, the measured pressure and the actuator converge
here.
Tasks
- Measures the flow of the fed in drinking water
- Measures the pressure on the supply system's pipes
- Records the position of the plunger valve
- Meters the operating hours of the actuator
- Provides measuring data with a local time stamp and stores them in a zero-voltage buffer until they have been successfully transferred and archived to the central station
- Can send specific operating statuses to a cellular phone number as an SMS alert
- Optional: A pressure sensor that is moved into the distribution network (critical point) communicates with the PLC through cellular technology
Inexpensive Installation
Underground engineering is required for the installation, but compared to the large savings potential, the initial investment is very small. We will help you determine the right place for the installation and create a list of the required activities. You will receive a proven, total system consisting of a plunger valve, pressure sensor, flowmeter, a programmed controller and, optionally, a cellular modem to transfer data to your central station. In addition to the usual quality tests performed at our facilities, the system is put into operation at your site by one of our qualified engineers. A training course for your engineers is also part of the package.
