Digital Flow Monitoring of Chilled Water Systems

larsHVAC systems are potentially very wasteful of energy; poor chiller and heating plant performance, unnecessarily high pumping costs, distribution losses, poor pressure and temperature control, blockages, faulty valves, poor commissioning etc.

“You can’t manage what you can’t measure. FloCon Watchman delivers the measurement.”


Real-time data on:

  • Terminal unit flow rates
  • Terminal unit flow and return water temperatures
  • Energy consumption

Which delivers:

  • Professional HVAC management
  • Better indoor climate
  • Cuts unnecessary energy wastage

Watchman BMS Interface

1297679417The interface monitors the flow and return temperatures to terminal units. The Interface exports this data and the Ultrasonic flow and energy meter data to the BMS in Modbus.

Locating valves at terminal units in congested voids

crossLocating test points, strainers, drain, isolating, flushing, regulating and control valves around terminal units is both impractical and costly in terms of commissioning time and maintenance!


Engineered solutions for hydronic systems

FloCon commissioning modules
provide a centralised ‘header’ for fan coil units, radiant panels, chilled beams or heating systems, acting as a distribution hub for a group of terminal units. Each module incorporates all of the valves required for commissioning and operation. FloCon modules can be sited in an easily accessible location so that hydronic commissioning and maintenance can be completed from one practical access point.


FloCon modules at a glance

FloCon – An engineered solution

  • Ideal for low flow heating systems
  • Variants for all terminal units
  • Easy access for commissioning
