DESCRIPTION: An electronic control panel used in conjunction with
one pulse meter (a water meter with pulse output proportional to
flow rate) which is installed on the incoming water supply at the site
boundary or at the building intake - in accordance with BREEAM
requirements.
The control monitors the flow of water through the meter over a
preset period of time and raises an alarm in the following situation:
When a continuous flow of water passes through the Main (M1)
water meter above a preset maximum for a preset period of time.
By setting realistic flows and time periods (allowing for usual
fluctuations in consumption) any increase above these norms may
be detected and dealt with – saving water and limiting damage
caused by a major leaks.
