ERL manufactures various types of LEVEL ALERT™ Liquid Level Sensors which provide reliable high level and overfill protection in accordance with 46 CFR 39.20-9 (b).

We manufacture different types of Liquid Level Sensors, because not all cargos and all vessel requirements are the same. Each type offers unique advantages for different cargos and different vessel configurations. All ERL Liquid Level Sensors are 100% compatible with all other ERL Liquid Level Control System Components and will integrate seamlessly no matter what your particular needs are. The following pages describe the various components of the ERL Liquid Level Control System.
