Technolog Regulo PRV Controller

Technolog designs and manufactures battery-powered data loggers and electronic pressure controllers for water and gas distribution, with over 40 years of experience. Its head office is in Wirksworth, Derbyshire, United Kingdom, with a second office in Paris, and the site states it is part of AMETEK.

Regulo is an electronic controller connected to most types of pressure reducing valve. It offers time-based, flow-based and closed-loop control, where Cello data loggers at critical points give real-time feedback. It has an integral multi-channel logger, transmits over 2G, NB-IoT or LTE Cat M1 and is managed through the web-based UtiliCore platform.

• Valve compatibility: connects easily to most types of pressure reducing valve.
• Control modes: time-based, flow-based and advanced closed-loop control.
• Closed-loop feedback: uses real-time data from Cello loggers at critical points.
• Remote configuration: downstream pressure profiles set remotely.
• Communications: 2G SMS/GPRS, NB-IoT and LTE Cat M1.
• UtiliCore: web-based remote monitoring, control and alarms with threshold profiles.

Time-based or flow-modulated pressure reduction at DMA inlets of provincial water companies in Vietnam. Closed-loop control that holds pressure at a critical point in hilly supply zones. Remote adjustment of pressure profiles for night-time leakage reduction.

Pressure control reduces leakage and burst frequency and gives calmer network pressures. The hydraulic-less design needs no filters and keeps maintenance low. Downstream pressure profiles can be changed remotely without site visits. Lower pressure stress may extend the expected life of the distribution network and reduce capital expenditure.

Pressure management is a common first step in non-revenue water programs because lower pressure reduces leaks and bursts. Vietnamese water companies that have formed DMAs often still adjust PRVs manually. Controllers with NB-IoT or LTE connectivity suit networks where cellular coverage is available.

Head office in Wirksworth, Derbyshire (UK) with an office in Paris; part of AMETEK; first Cello unit launched in 2000 and gas-sector work since 1981. A 2025 project supplied 40,000 Cello Sewer Alarm devices to Yorkshire Water. Founding year not stated.
