Maintaining the correct pressure in water supply networks is one of the biggest challenges for operators. Too high pressure leads to water loss and failures, too low pressure leads to customer dissatisfaction. The solution to this problem is telemetry modules, which not only monitor but also actively control pressure reducing valves (PRV). 

One of the most advanced devices of this type is the MT-718 – a telemetry module in an IP68 enclosure, which, thanks to built-in PRV algorithms, acts as an intelligent pressure regulator.

The device controls the output pressure from the PRV valve, modulating it according to the adopted control method. The valve is opened and closed by pulses generated at the module outputs, which allows for precise control of the valve position. 

The MT-718 offers two control modes: 

• PRV time (time control)
  The pressure is regulated according to a pre-set hourly schedule. The operator can programme different pressure values for day and night. The result? Stable pressure during peak hours and water and energy savings outside of them. 

• PRV flow (flow control)
  In this mode, the device adjusts the pressure in real time, based on data from a flow meter installed upstream of the valve. If the flow increases, the pressure increases with it. When it decreases, the regulator automatically lowers the pressure. This solution is particularly valued in large and variable water supply networks. 

In both modes, the device uses control tables that define the desired pressure value as a function of time or flow. The regulator calculates intermediate points linearly between the set values, which allows for smooth pressure adjustment. 

The MT-718 is equipped with an advanced alarm system that immediately detects and signals abnormal operating conditions. The device monitors the parameters of its internal components (e.g. battery voltage, GSM signal level, temperature) as well as process parameters. If any of them exceed the normal range of values, the system automatically generates an alarm and sends it to the operator. 

In addition, classic alarms such as high flow, low pressure or deviations from set control values are also supported. In critical situations, the MT-718 can automatically close the valve, protecting the network from damage. Operation can be restored locally, remotely (SMS, packet data transmission) or automatically after a specified time. 

The device has been designed with operator convenience in mind. Control and data logging parameters can be set very easily: 

• locally – using configuration software run on a PC, 

• remotely – thanks to packet data transmission in the GSM network, provided by Orange, PLUS or T-Mobile operators. 

A dedicated, free MTManager application is used for this purpose. 

This allows the operator to respond in real time, change schedules or adjust control parameters without having to send a team to the field.

The MT-718 is a device that combines the functions of a data logger and an intelligent pressure regulator. Thanks to PRV time and PRV flow algorithms, remote GSM communication and built-in security features, the module allows water supply network operators to work more efficiently, safely and cost-effectively. 

It is a step towards modern, intelligent water infrastructure management, where pressure stability goes hand in hand with savings and reliability.
