NEW! Series SBLT2 Lightning Protected Submersible Level Transmitter


The Mercoid Division of Dwyer Instruments is offering a new and robust submersible level transmitter, the SBLT2. The SBLT2 is manufactured for years of trouble free service and is ideal for non-fouling applications such as groundwater remediation, well monitoring, process fluid tanks, and water tanks.

The SBLT2 is designed to measure the height of liquid above its position in the tank, sump, or pit. Featured in the SBLT2 is a snub nose so that the unit can be dropped to the bottom of the tank, lightning surge protection, and 0.25% accuracy. The cable is vented to atmosphere for barometric pressure compensation and can be bought in ETFE or polyurethane.

Priced from $350.00 for a 5 psi (11.54 ft wc) model with 40 feet of polyurethane cable the SBLT2 is a great value.
