SOFREL - Model LS-V -Data Logger for Controlling Pressure Control Valve

It can be used to:

• Reduce the volume of leaks by lowering the pressure in the network, at night for example,
• Improve network longevity by reducing the intensity of peaks in pressure,
• Control water circulation within the network.

The data logger operates a Latch solenoid for valve control, in 2 modes, which can be used separately or simultaneously:

• By time/date: the data logger controls the valve (reduced or normal pressure) based on a 24-hour configurable period,
• By threshold, according to flow or pressure: the data logger calculates and archives the average flowrate based on «meter» data; when flow is higher than a user-configurable threshold, LT-V sends a command to the valve. It can also control the valve using a pressure threshold.

• In addition to its valve control function, SOFREL LT-V measures flow and pressure, which it records according to a configurable archiving period, and transmits its data by GPRS connection to a centralisation system (SCADA central station, WEB LS server, etc.).
• Should there be any alarm (flow or pressure thresholds being exceeded, for example), LT-V can also send an alert message by SMS
