Radio teleswitch is a method for broadcasting messages using the 198 kHz (BBC Radio Four) transmission system.
We don't believe in technology for its own sake, but we always strive to use the best methods available, particularly for communications between meters and the central station.
We have used modems since the very earliest days of two-way communications using Public Switched Telephone Networks (PSTN).
We really appreciate technology when it lets us do something better than before or something completely new. Low-power radio (LPR) technology lets us do both.
We have always believed that metering is just the first link in a chain in which communications is the most difficult part to implement.
Conventional pump efficiency meters require the flow to be measured. This is often difficult to do on site and is subject to non-linear errors.
As implied by our name, security is central to everything we do. Security means protecting equipment and data from accidental damage or deliberate interference.
We have been involved with keypad prepayment technology for more than 20 years.
We were one of the first companies to implement a fully integrated electronic payment metering solution. Our first keypad prepayment energy meter was launched more than 20 years ago.
