Tokyo Keiso TGF7200 Guided Wave Radar Transmitter
Made in Japan
Manufacturer: Tokyo Keiso
Model: TGF7200
The TGF7200 is a 2-wire continuous level measuring instrument using TDR technology. The simple and compact design suitable for tank-top installation with no moving parts achieves high cost performance with maintenance-free and low-cost installation. Thanks to a variety of probe types such as coaxial, single, and twin probes, this continuous level meter can measure various measuring objects such as liquids and slurries in applications such as the measurement of the liquid level and the interface between two liquids. The keypad operation on the front display allows easy parameter setting including zero-point adjustment and measurement range. This level meter is suitable for level control of buffer and sump tanks, as well as capacity management of storage tanks.
Features
