Level Guided Radar with 2-wire system Micro Pulse Level MeterTGF1100



*Specifications are subject to change without prior notice.

The TGF1100 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. This continuous level meter become applicable to wide services inclouding various liquid and powders using by coaxial and single cable probes. The keypad operation on the front display allows easy parameter setting including zero point adjustment and measuring range. The micro pulse level meter issuitable for tank and silo inventory for liquids and powders as well as level controls of the intermediate tanks and vessels.


  • · Wide applications by TDR technology
  • · 2-wire loop powered system with less cable and low installation cost
