1. General Introduction
Tokyo Keiso FM MAG gauge is a float type metal tube level gauge, liquid level is indicated by clear and visible color flappers which eliminates problems likely in indication by existing glass gauges. In addition, special material of PVC, Fluorocarbon resin, Glass lining and etc. Alarm contacts or analog output can be additionally provided for remote monitoring and control purpose. It mainly features as below typical characters:
-Free from breakage and leakage!
-Clear visible indication by color flappers.
-Suitable for high press. and temp. HPGCL certified versions available.
-Various materials available.
-Additional functions of alarm and analog output available.
