Rochester LPG Measuring Equipment Level Gauge 6300 Series
Rochester LPG Measuring Equipment Level Gauge 6200 Series
The T/LL70 series is a comprehensive range of vertical float level switches designed around the proven and reliable magnet and reed switch principle.
Comprising many build variants, the T/LL70 is customised to each application by means of materials, level adjustment, connection, thread and reed contact specification etc. The data below gives some sense of the numerous combinations, but some interdependency exists with regard to the materials of construction.
