AMETEK Power Instruments, a supplier of electric power measurement instrumentation, has added a GSM (Global System for Mobile) cell modem communications option to its Ci20 and JEMStar multi-function revenue meters, that provides wireless communications between the meter and a remote device. GSM complements the two meters’ existing communications capabilities, which include RS-232/485 serial ports, Ethernet and standard telephone modem. The cell modem operates over the entire meter power range (55 to 530 VASC), and is ‘under the glass’ for added security.

The Ci20 and JEMStar meters are available with any meter protocol (DNP, Modbus, ANSI Tables and MV90). Each features a Windows-based software configuration wizard that reduces configuration time, minimizes errors and allows easy installation of upgrades.
