SmartPoint™ is an intelligent alarm processor built into every LEAKNET™ system. It is a versatile and powerful way of eliminating false alarms.

A SmartPoint is a collection of PPA points and MassPack accumulators configured by the user into a logical unit which alarms only when all specified conditions are met. You can build fast and fail-safe alarm schemes, or you can build conservative, false-alarm-free schemes – it's up to you. These are easy to change as your needs change.

SmartPoint is LEAKNET™ intelligent alarm processor and is LEAKNET™ most powerful way of eliminating false alarms.

Each SmartPoint operating within LEAKNET™ is created by defining a logical relationship among a collection of PPA and/or MassPack points.  Any SmartPoint can use any PPA point and any MassPack accumulator, and any other configured  SmartPoint to create this logical relationship.

Each SmartPoint monitors all of its component points to see if the alarm logic of the relationship is satisfied.  When it is, a fully qualified alarm is provided for the operator.

SmartPoint Features

PPA points,  MassPack accumulators and other SmartPoints may be used over and over to create as many SmartPoints as you need.

Configuration of SmartPoint arguments is done in a point and click editor window and takes only minutes to complete or edit.

Using SmartPoint

Suppose you want to monitor a simple pipeline running between a pair of pumps and several tanks 20 miles away.  There is one instrument, a pressure transmitter, near the pumps.  The line has two sources of nuisance alarms: pump changes and tank switches.  The following example shows how to use SmartPoint in two steps. 

First, to eliminate nuisance alarms associated with pump changes.

  • Add a PPA flow point near the pump using an inexpensive clamp-on flow meter
  • Set this new PPApoint to alarm on an increase in flow.  (If the line develops a leak, flow suddenly increases as product begins to leave the line through the new opening.)
  • Configure a SmartPoint to alarm when the pressure point sees a decrease AND the flow point sees an increase.

Pump Operations NEVER create this combination of conditions, so the can NEVER cause a false alarm.

Second, to eliminate the tank false alarms,

  • Add a PPA flowpoint near the tank manifold using an inexpensive clamp-on flow meter
  • Set this new PPA point to alarm on a decrease in flow.  ( Here if the line develops a leak, flow suddenly decreases as product begins to leave the line through the new opening.)
  • Add the new PPA flowpoint to the SmartPoint.  Now an alarm occurs only when the pressure decreases and the pump flow increases and the tank flow decreases.

 The logical argument defines the only condition associated with a leak on the line.
