vl WASP Wireless Acquisition Standard Protocol

Sentry Telemetry is a key member of the water utilities' Wireless Acquisition Standard Protocol WASP development committee, co-ordinated by the UK's Water Research Council plc (WRc).

WASP is the first industry standard protocol for short-range wireless communications to enable interoperability of sensors and equipment from approved manufacturers.

The monitoring system will consist of one or more sensors to monitor key parts of the process or equipment and the sensors will be connected to or be integral with a radio. The sensor radios will communicate with a communications hub installed at the site.

Our radio and GSM products are currently being re-engineered and trialled to ensure WASP complaince, even though the protocols and standards are still at draft stage.

Sentry Telemetry can provide a range of communication equipment, sensors and meter reading devices and is keen to partner with industry-leading instrumentation and equipment manufacturers.
