Pressure Transient – Transient Data Logger

Manufacturer: HMW
Pressure Transient – Transient Data Logger Pressure Transient is a high-performance data logger designed for accurate monitoring of pressure transients in water supply networks. With fast logging capability up to 100 samples per second, advanced cellular telemetry (4G / LTE-M / NB-IoT with 2G fallback), and innovative event window selection, the device allows operators to transmit alarm data together with a selected window of high-speed data before and after a transient event. This enables immediate identification of surge events (water hammer), helping to prevent pipe bursts and infrastructure damage.
