Advanced Information Networks has recently set up a monitoring system using the XE8000 to keep records on the flow rate and volume pumped from a water well at Christchurch Airport.

Consent to draw from this well was granted subject to various specified conditions from Environment Canterbury. These conditions state that water shall only be taken 'at a rate not exceeeding 20 litres per second, with a volume not exceeding 4,641 cubic metres in any period of seven consecutive days.

To ensure consent conditions are met, the XE8000 SMS Controller monitors this well and sends its readings to the Internet via SMS messages. This saves many hours in time as figures can be checked from an office rather than field technicians having to make regular visits on-site to check this information.

The current water usage can be queried at any time by sending a Txt message to the SMS Controller. The SMS controller can also send SMS or email alarm messages to the mobile phones and PCs of relevant personnel. This allows instant detection if conditions change at the site or if a fault occurs.

By using the SMS Controller readings are taken automatically at set intervals and are free from human error. The XE8000 interfaces directly to the water meter, in this case a Helix 4000, and uses a Wavecom modem to transfer data.
