Pressure management system Pegasus 2

Manufacturer: HMW
Get a Quote
Pegasus 2 is a remotely controlled pressure management system for water supply networks, providing precise PRV (Pressure Reducing Valve) regulation based on demand or time settings. The system allows users to define specific time periods for pressure reduction or increase, as well as regulate pressure based on flow or a combination of both parameters. The system utilises an integrated GSM modem with LTE-M, NB-IoT, 4G, 3G and 2G connectivity options, ensuring secure two-way communication and full remote control via the PressView Cloud platform.
Description

System Overview

Pegasus 2 is a remotely managed PRV control system offering time-based and flow-based pressure modulation to reduce leakage and burst frequency.
