Traditional methods have been used to try and resolve the issue of unauthorised valve operation without much success. The Scorpion is a low cost device which is located onto the valve dolly, which has to be removed before the valve can be operated, the result of which would generate an immediate alarm message back to the office. Valves operated without authorisation can cause many issues which may result in unnecessary work being carried out to determine and resolve these problems which can be costly and time consuming.
Valve Alarm Monitoring
Strategic valves are commonly found within all water networks and the accidental operation of these valves can have major implications to both the water supply company and the customer. As the result of operating these valves the control of the network or quality of the water delivered to the customer could be affected as follows:
Water quality due to contamination and discolouration of water supply or uncontrolled mixing of water sources.
Pressure imbalances and consequential damage (pressure surge) can occur when rapidly opening a valve which can cause an increase to burst rates.
Zone integrity due to the effect on leakage meter readings, the result of which is unnecessary effort and expense in trying to locate a burst that doesn’t exist
Integrity and status of the water supply is altered which could increase operational costs.
The Scorpion will act as a deterrent to operating critical valves and monitoring the operational use of divisional / boundary valves without following the required procedures.
In addition the Scorpion can be used to monitor the illegal use of water through fire mains, unauthorised operation of meter bypass valves and illegal use of hydrants.
The Scorpion utilises SMS text messaging data to transmit alarm and health checked messages to your office (5 year battery life) to give details of the sensor status and operation. Each message will include the valve details (customer definable), alarm condition or health check status, date, time, battery condition and message count.
The main features of utilising the Scorpion Valve Warning System is that immediately the sensor is removed from the valve, an alarm message is sent to the designated address and a new message is sent to confirm when the sensor is re-fitted. However if the sensor is not re-fitted, an alarm message will be sent every hour (for up to 6 hours from time of removal) and then once every 24 hours until it is re-fitted. A monthly health check is sent to show that the unit is still operational as the unit will only be removed on rare occasions.
