HWM - Pressure Transient Telemetry Data Logger
Pressure Transient is a highly-versatile data logger designed for effective network transient logging. Featuring advanced cellular telemetry and innovative ‘event window selection’ the operator can now send transient alarm information and a selectable window of fast logged data before and after the event, or for set time-based windows. Transient logging is no longer a purely survey operation, but can now be part of permanent network monitoring for standard flow and pressure logging. Transients are immediately identified so remedial action can be taken, avoiding bursts and infrastructure damage.
Pressure Transient transmits data through an integral modem with GPRS/2G, 4G, LTE-M (Cat-1) and other NBIoT cellular options available.
In addition to pressure transient logging, flow and pressure channels can be added to log other network parameters (Enhanced Network Logging) for comprehensive transient and general network monitoring. Sampling can be operator selected through a wide range of options to 100 samples per second.
The full range of HWM external battery packs can be connected to power accelerated dial-in regimes and extended periods of maximum sample rate. These can simply be exchanged on site as required.
