Buying Process Description:

The final user Local buying process is:

  1. Buys any number of Kilowatt/Hour at any distribution point, for a given ZSME2 Meter.
  2. Gets a secure ticket with a printed barcode.
  3. Goes home and inserts the ticket into the Terminal's Barcode Scanner compartment.
  4. Pushes the [START] key at the Terminal. Reading takes less than 2 seconds and there is an audible warning when completed.
  5. The Terminal updates the register and the display with the new values and dates.
  6. Finally, the user removes the ticket from the Scanner compartment and is free to discard it if he wishes.

The final user Remote buying process is:

  1. Buys any number of Kilowatt/Hour at any distribution point or via Internet, for a given ZSME2 Meter.
  2. The given ZSME2 Meter is remotely and immediately accessed.
  3. The given ZSME2 Meter updates the register and the display with the new values and dates.

General System Specifications

  • Proprietary leading edge technology with last generation hardware (UL and CSA approved minimum) and firmware.
  • Completely TAMPER-PROOF. All tampering attempts are saved in memory and immediately reported via wireless interface when possible.
  • Built-in Wireless Modem 3G and 4G compatible that can be accessed remotely at any time to register new purchases, get reports, check status, monitor operations, define or modify settings, block/unblock Electric flow, etc.
  • Built-in USB 3 interface for local testing, downloading reports and in general for the same operations that can be performed remotely via Modem. For use by authorized personnel only.
  • Built-in 4 (Four) MB of rewritable flash memory with eight (8) years data retention minimum, to store tampering attempts, buying history, settings, etc.
  • Built-in Barcode Scanner.
  • Built-in graphic LCD display to show status, balance, last purchase information, available Watts, etc.
  • Each unit is identified with a unique, non-programmable, 10-digit factory-defined code.
  • Indoors use only
  • Built-in electronic switch that can be operated remotely or locally by authorized personnel only, to block or allow Electric flow independently of any settings, consumption status or the normal flow control described below. This function requires an special key code only available to selected staff inside the provider organization.
  • Completely sealed stainless steel in-wall enclosure with no acceptor or card grooves.
  • Dynamic encryption with virtually impossible to duplicate codes. Trillions of combinations with proprietary 1024 bits encryption algorithms for the highest international safety index.
  • Proprietary LAMP server application to generate encrypted ASCII text codes or encrypted Barcodes.
  • English and Spanish versions available for Meters displays.

Electric Flow Control (Dream of goverments and suppliers!)

  • Monitors Electric consumption and stops the flow automatically when the programmed limit is reached. This feature effectively gives the government, the power supplier or the user (When "User Mode" is enabled) the ability to rationalize consumption in a global, sectorized or case by case manner.
  • Can be programmed remotely via the wireless interface or locally through the USB interface.
  • Measure and Selling Unit: Kilowatt hour (kWh).
  • Programmable Consumption Period: Day (Default), Week or Month. Only one value can be programmed. NOTE: Daily control is the best option because the count is cleared at the beginning of each period. If daily control is programmed and the flow was blocked in the previous day, it is enabled again for the new day.
  • Programmable Maximum Consumption in Kilowatt hour (kWh) per period. i.e. 20/Day = Maximum 20 kWh per day
  • Programmable Maximum Selling Units per month. Default 500.
  • Programmable Minimum Selling Units. One minimum.
  • Programmable audible alarm to warn Maximum Consumption limit is approaching.

Meter Default Specifications
(Custom specifications are accepted for 20+ units orders - Price may vary)

  • Active Energy Meter, Class 1.0
  • Complies with IEC 62053 Standard
  • Current Rating = 5(60) A
  • Accuracy ≥ 0.5%
  • AC Frequency = 60/50 HZ
  • AC Voltage = 110/220 Volts
  • Current Sensing Method = Transformer
  • Dielectric Withstanding > 4 KVrms
  • Isolation > 10000 Volts
  • Switching Device = SSR
  • Maximum Power Switching = 10 KW
  • Total Power Consumption < 0.5 Watts
  • Metering Unit = 1 W/H
  • Working temperature = -20 to +60 °C


USER MODE is a special form of operation to allow users to benefit from the ZSME2® Meter system advantages and sophistication as a stand-alone unit. EXCEPT FOR THE METER system, that still can be used by the service provider to accurately and safely monitor and register user consumption, all other control functions are managed directly by the user.
