The Miniature WTMN 3000 Series submersible transmitters are specifically designed for depth and level measurements of groundwater, wastewater and sea water where space is very limited. The housing diameter of 0.39 inches offers the user an ideal high performance level measurement in small diameter, i.e. 1/2” monitoring wells, stand pipes and bore holes. The titanium construction and integral polyurethane cable provide a reliable long term solution for these difficult-to-measure applications. Kevlar is used as a cable reinforcement to avoid any elongation, particularly when long lengths of cable are required for deep wells. Long term stability of typically ±0.1% per year also contributes toward a maintenance-free installation.
