Monitoring for district heating and cooling
Find the leak before it becomes an outage.
Pipeguard delivers complete monitoring systems for district heating and cooling networks: alarm modules in the field and the PGweb web system that brings alarms, readings and history together in one place.
Trusted by energy companies across Sweden
Monitoring built for the field
Our modules are designed for the tough environments they work in, built on more than 45 years of experience. Sensitivity is their strength and reliability is their signature. Whatever you need to know about your distribution network, we can help you capture it.
- 1–8
- pipes per pulsPG, with TDR fault location
- 10 år
- battery life in the CC58 chamber alarm
- IP 67/68
- rated MT modules, built for vaults and chambers
What we monitor
Moisture and leaks
Alarm wires are measured in a loop, so length doesn't affect the readings.
Fault location with TDR
Pulse reflectometry shows the distance to the fault and stores the curve for analysis.
Chambers and vaults
Water level, RH%, temperature, lid and tamper alarms.
Pressure, flow, temperature
Supply and return pressure and temperatures, straight to the control room.
Old pipes without alarm wires
Acoustic leak detection with microphones where there is no wire to measure.
Pumps and boilers
Status and alarms from equipment in the network.
PGweb – the whole network in one view
System Pipeguard is a web-based monitoring system that collects readings from alarm modules and other sensors and presents them so you get an overview fast and can make the right decision.

Moisture alarm for 2–4 pipes
microPG / miniPG
Compact alarm unit that measures alarm wires in a loop, so the same amount of water gives the same reading wherever the fault is. microPG handles two pipes or loops, miniPG four.

Fault location with TDR, 1–8 pipes
pulsPG
Locating alarm unit with time-domain reflectometry (TDR). A main unit with 1–8 measuring modules connected directly to the pipe. Also measures deviation from the reference curve and the distance to the fault.

Chamber alarm with up to 10 years' battery life
CC58 ChamberCheck
Monitors chambers and vaults: RH%, temperature, water level, floor temperature, and pressure and temperature on pipes.
