5 year battery life
Radcom data loggers and controllers are designed to give an typical battery life of 5 years.
Standard logger configuration
A 5 years battery life is achievable when a Radcom logger is configured with a "15 minute Sample Rate" (ie time between recordings) and when using reed switch type digital flow sensors or standard mV type pressure transducers.
4-20mA loop systems
It is possible to sense 4-20mA current loops whilst retaining the 5 year battery life, where the 4-20mA loop is externally powered. Some special application 4-20mA loop systems can be powered from the Radcom logger but with reduced battery life.
Kent and other HRP digital flow sensors
High power consuming devices such as Kent HRP (High Resolution Pulser) digital flow sensors will reduce the Radcom battery life significantly. (HRP = 100 pulses per revolution)
PD100 and PD10 Radcom sensors
Radcom developed high resolution pulser sensors with 100 pulses per revolution (ie the same as the Kent HRP) but with much lower battery consumption. The more recent PD10 (10 pulses per revolution) sensors have further reduced power demands, to enable 5 year battery life when powered from a standard MultiLog data logger. When connecting PD10 to a LoLog, Radcom recommend either a PD10 supplied with an inline battery box, or to order a special Orange painted LoLogLL with increased internal battery size.
PSTN Telemetry loggers
Loggers with an integral Land line modem can achieve a 5 year battery life with a single daily data download. If the logger is contacted many times each day or held in communications regularly for long periods may suffer reduced battery life.
SMS/GSM Telemetry loggers
Loggers with an integral cellular modem can also achieve a 5 year battery life, if the rated "Time Window" (ie the time that the logger's modem is powered in receive mode) is not exceeded by user configuration settings. The following logger product variants are available with increased battery capacities: 2 hour, 4 hour or 10 hour Time window / 24 hour day.
External power
Recent MultiLog data loggers can be connected to an external power source, via the 10 pin Military communications connector. Mains power supply units or other 12 volt power supplies can be used to provide 24 hour communications (ie similar to PSTN type communications).
