The Pressure Transient Data Logger from Fluid Conservation Systems monitors networks for damaging pressure transients, combating water hammering. With a five-year battery life, fast data sampling and large memory, it is suitable for long-term surveys and rapid troubleshooting. It has 4 GB of flash memory and uses advanced data compression algorithms to store up to 8 billion readings. It can operate effectively in the field for long periods. Reduction or elimination of pressure transients can significantly improve asset life and reduce burst frequency. The device comes with an aluminum case containing the data logger, pressure transducer with quick-fit connector, download lead, software and full documentation. 800/531-5465; www.fluidconservation.com.
