Reliable Float Level Monitoring, Wireless and Hassle-Free

Overview:

Accutech FL10 Wireless Float Level Field Unit

The Accutech™ FL10 wireless float level field unit interfaces with the Electrolab™ Model 2100 digital level sensors to provide single or dual fluid level and temperature data across a wireless connection to an Accutech base radio. The FL10 head unit and Model 2100 level sensors are offered as separate products, which are then connected together by the end user. This system is suitable for a variety of liquids, including crude oil, condensate, diesel, gasoline, kerosene, and water.
