TGR4500

Guided Radar with 2-wire system Micro Pulse Level Meter

TGF2200

The TGF2200 series is a unique 2-wire continuous level-measuring instrument using TDR technology.

The simple and compact design suitable for tank-top installation with no moving parts has a high cost performance with the maintenance-free and low cost installation by the simple 2-wire loop powered system. Thanks to the coaxial probe, single probe and twin probes this continuous level meter is applicable to wide services including liquids, slurries, powders and granules. The keypad operation on the front display allows easy parameter setting including zero point adjustment and measuring range. The micro pulse level meter is suitable for tank and silo inventory for liquids and powders as well as level controls of the intermediate or underground tanks.
