Meet ELMO, meaning vigilant and secure, describing exactly the purpose of our ELMO-IT energy monitoring range of wireless and data loggers.You’re switching off your PCs when not in use. You use motion detectors to control the lighting in the offices. The thermostats have been turned down a degree. How else can you improve energy efficiency?
Efficiency is becoming an economic as well as an environmental necessity. A monitoring system, logging energy usage over time and allowing statistical analysis of kilowatts consumed, can quickly identify ‘hidden’ excesses, resulting in significant savings within weeks of installation. The data can then be used to provide logged records as evidence of sustained energy reduction over time.
Jekyll offer a variety of options for monitoring - via radio - the energy use of a site. Radio telemetry requires no additional wiring to be installed. The proven radio technology used by Jekyll has been in use for over a decade, reliably monitoring the environmental conditions of warehouses, distribution bases, laboratories and production lines in the pharmaceutical, food preparation and aeronautical industries.
Current Monitoring
Elmo radio transmitters, fitted with either a one or three phase current monitoring sensor, are clamped to the mains power cables. These transmit the readings back to an Ethernet enabled receiver (the NRG - Network Radio Gateway) which is connected to a LAN or WAN. The NRG is interrogated for the data by the Radiolog software and the data filed on a server. Both live and logged data can be viewed not only on site but at different offices via the internal LAN or external WAN.
Multiple NRGs can be included on a single system, allowing data to be collected from multiple sites simultaneously. This system provides a quick and simple overview of energy use based on instantaneous current metering. More detailed data can be collected using the Utility Meter Monitoring option.
Utility Meter Monitoring
This uses the Elmo radio transmitters connected to the output(s) of the utility meter. The units measure and transmit the cumulative number of pulses output by the meter back to the NRG where the data is collected. The data is then collected and displayed via the software. There are two types of Utility Meter at present:
• 1 channel, for use with electricity, gas and water meters
• 2 channel, for use with electricity meters which send 2 channels of data and a synch pulse
This system provides a detailed analysis of the metered usage of utilities and can be used to produce refined energy management strategy.
Each logger has up to four input channels, a USB connection, on-board calibration data and 128K memory as standard (256K optional). The inputs can be mounted internally to the transmitter body, externally on the case or remotely on a probe.
The transmitter ID, transmission speed and calibration data is programmed into its on-board memory using Radiolog 8, a software package which automatically recognises the type of unit connected to the PC via the USB lead.
Other Options
If a network connection for the NRG is unavailable, the data can be collected and downloaded using the LRG (Local Radio Gateway). This is a logger which connects to a PC via a USB port or GSM. The software can still run on the network and can be configured to automatically download the data.
