HWM has launched an intrinsically-safe range of data loggers suitable for the gas industry, after 30 years developing monitoring, telemetry and data logging solutions for the water market. The new Intelligens range will offer a number of variants suitable for gas network monitoring and automatic meter reading.

The new data logger is certified to ATEX Zone 0 and suitable for applications including gas network pressure surveys, governor / regulator station monitoring and extremity point monitoring. Thanks to multi-input functionality, the Intelligens unit can be supplied with multiple digital pressure inputs, in addition to temperature, flow and state recording. Data is transmitted via GPRS with an option for SMS backup. A 3G modem variant is also available.

The unit’s telemetry options, robust construction and five-year battery life make it particularly suited to applications requiring an accurate and reliable monitoring system on sites which are remote, hard to access or visited irregularly. Advanced features such as digital pressure transducers ensure long-term stability with negligible drift.

The logger’s two-way connectivity allows for remote programming and advanced interrogation, avoiding the need for unscheduled and expensive site visits. An advanced alarm template can be uploaded to enable an alert to be sent to multiple recipients. When an alarm event occurs the unit’s accelerated sampling frequency and data transmission options allow the user to monitor and respond to changing conditions with much greater confidence.

The low-power electronics ensure a five-year battery life, even after increased data transmission rates during alarm conditions are factored in. The internal battery can be supplemented with solar power or external battery packs.
