Digital Flow Monitoring of Chilled Water Systems
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
HVAC 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.
Watchman BMS Interface:
The 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.
“You can’t manage what you can’t measure. FloCon Watchman delivers the measurement.”

Engineered solutions for hydronic systems
Locating valves at terminal units in congested voids
• 22% saving on installation time
• 57% saving on flushing horizontal mains pipework
• 77% saving on flushing fan coil unit circuits
• 56% saving on commissioning
A BSRIA study
using FloCon
modules showed
significant time
savings compared
to locating valves
at terminal units.
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.
(4 fan coils, 8 branch tees, min 24 joints)

Locating 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!

Other benefits include:
• Supports use of pre-fabrication and factory testing
• Modules are housed in pre-insulated, vapour-sealed boxes
• Optimises on-site use of skilled operatives
• Enables accurate commissioning, even with ultra-low flows
• Less disruption to conditioned space during maintenance
• Facilitates post-commissioning ‘fine tuning’
• Energy saving with variable speed pump control
• Ideally suited for use with flexible piping system
Ideal for low flow heating systems
Variants for all terminal units

Designed for energy metering, change and churn
Terminal unit groupings
Potential future groupings to reflect change in office zone partitioning
• FloCon Watchman modules are produced
with seven ports as standard.
• Modules are then configured to match
the required terminal unit layout.
• Unused ports are blanked off for
potential future use.
