The Willowglen FloLog™ Gas Well Flow Logger is a flexible, cost effective and extremely energy efficient solution for remote gas well Electronic Flow Measurement (EFM) applications. With its hazardous area certification and battery operation, the FloLog™ device is ideal for use at well heads as a low cost, much higher accuracy and more convenient alternative to a chart recorder. The FloLog™ device measures the orifice static pressure and differential pressure with a multivariable transducer and also includes a probe for temperature measurement.The extreme low power operation of the FloLog™device eliminates the need for expensive solar panels because the device can typically operate for a year on a set of three standard AA batteries. Gas measurement readings are stored in non-volatile Flash- memory with a 36 day capacity. Periodic data retrieval is available through the built-in infrared port to an on-site laptop computer or a Pocket PC PDA. A serial port also allows the FloLog™ device to communicate with a SCADA host computer. Combined with Willowglen’s companion FloLink™ Radio Communication Unit, a completely battery powered RTU/Radio solution can be achieved.
