Our Energy Metering Projects
- Single Phase Multi-Parameter Energy Meter (Class 1)
The design is based on Cirrus Logic&trade metering chip & Microchip&trade PIC 16F72 Microcontroller. This is a high end meter. It complies to all the standard parameters any electricity utility company asks for. Other features include, all the tamper detection methods, all electrical measurement parameters, load survey tables, Real Time Clock (RTC), Time of the Day (TOD) metering, Switch Mode Power Supply (SMPS) and Liquid Crystal Display (LCD) and two communication ports. These ports can be connected to a piggy back boards for Power Line Carrier Communication (PLCC) or Radio Frequency communication (RF) or Telephone communication (PSTN) or MODBUS&trade communication or Optical Communication or GSM communication or Local Area Network (LAN). These piggy back circuits are based on Plug & Play technique. Therefore it is possible to alter them even in the field. This makes a very versatile meter. The circuit has been designed to match the standard electronic meter cabinet as specified by Indian Electricity Utility Companies. These circuits are made using all Surface Mount Components (SMD) and has a built in protection for all surges and various electrical conditions in India. The design complies all the standard tests certification prevailing in India.
Products based on this design are presently sold in India.
- Tri-Vector Energy Meter (Class 0.5)
The design is based on AD&trade metering chip & Microchip&trade PIC 18F6270 Microcontroller. This is a high end meter. It complies to all the standard parameters any electricity utility company asks for. Other features include, all the tamper detection methods, all electrical measurement parameters, load survey tables, Real Time Clock (RTC), Time of the Day (TOD) metering, Switch Mode Power Supply (SMPS) and Liquid Crystal Display (LCD) and one Optical communication ports. The data can be downloaded to any standard Common Meter Reading Instrument (CMRI). The meter can be programmed and calibrated on production floor using a standard PC software. This makes a very versatile meter. The circuit has been designed to match the standard electronic meter cabinet as specified by Indian Electricity Utility Companies. These circuits are made using all Surface Mount Components (SMD) and has a built in protection for all surges and various electrical conditions in India. The design complies all the standard tests certification prevailing in India.
Products based on this design are presently sold in India.
- Retrofit Unit for Legacy Meter Communication
The design is based on Microchip&trade PIC 12F508 Microcontroller. There are any legacy meters which are used in electrical system. The common types are Electromechanical Meter or Moving Disk Meters. There are also vast number of Static Energy Meters. These meters do not have any communication capability for Automatic Meter Reading System. When the electrical system needs to be automated, then these meters also need to be added in the network.
The retrofit unit is designed to do just that. It collects the input pulses from the optical sensor by measuring the revolution of the rotating disk, or it measures the optical LED pulses from the electronic meter. The retrofit unit then converts the pulses into the energy units and then transmits them on serial port. The meter constant that is used for this conversion is user programmable. It can be programmed using a serial port. This port can be connected to a piggy back boards for Power Line Carrier Communication (PLCC) or Radio Frequency communication (RF) or Telephone communication (PSTN) or MODBUS&trade communication or Optical Communication or GSM communication or Local Area Network (LAN). These piggy back circuits are based on Plug & Play technique. Therefore it is possible to alter them even in the field. The design complies all the standard tests certification prevailing in India.
Products based on this design are presently sold in India
- Data Concentrator for Automatic Meter Reading Network
The design is based on Embedded Micorcomputer 386 design. The various meters in the network are to be read at a periodic interval with proper polling. The network can consist of a meters or retrofit unit for Legacy meters.
The data concentrator unit is designed to do just that. It collects the collected the data from various meters or the retrofit units on one serial port. It then transmits it on second serial port connected to central office of the utility company. Both These ports can be connected to a piggy back boards for Power Line Carrier Communication (PLCC) or Radio Frequency communication (RF) or Telephone communication (PSTN) or MODBUS&trade communication or Optical Communication or GSM communication or Local Area Network (LAN). These piggy back circuits are based on Plug & Play technique. Therefore it is possible to alter them even in the field. The design complies all the standard tests certification prevailing in India.
Products based on this design are presently sold in India
