Old PRI Meters, loggers and EASEII software

CALMU (Credit and Load Management Unit) was created in the 1980's and was the original Smart Meter. With internal storage of load survey and remote reading capability, CALMU made possible the opening up of the Electricity Supply Industry to competition Although out of manufacture for over 20 years there are still many CALMUs on supplies to commercial tenants.

Prime 500 set new standards for panel mounted meters. With the user friendly selector switch and a range of outputs Prime 500 is still to be found on many switchboards.

We offer a replacement meter and conversion plate package to allow for easy swap out of old Prime 500 meters for our latest Elite 400 series meters.

The original 96Din panel meters were the Elite700 Series and the Encore300 Series. Encore was a simple kWh meter with amps and vaults and a pulse output. Elite was a true multi-function meter with a range of outputs. After a few years the meters were rationalised and the Enocre range was dropped. Following further rationalisation the Elite was limited to two versions; the Elite 115 a multi-function Modbus meter and the Elite 120 a multi-function meter with both Modbus and pulse outputs.

Pactlan was a communications system allowing lCALMU, Premier, Sprint and Elite meters to be daisy chained together for interrogation by software such as EASEII. PRI also developed a datalogger that could be connected to a Pactlan network allowing pulsing water and gas meters to be monitored.

PRI developed a 8 channel and a 16 channel data logger.

EASE II Software in conjunction with Pactlan Networks, 8 & 16 channel data loogers and CALMU and Premier meters offered a comprehensive Automatic Meter Reading (AMR) system.
