FW-100 Series

OUTLINE

FW-100 is a balance weight, float type level gauge. Liquid level in

atmospheric tanks is detected by float and is indicated by the posi-

tion of balance weight against Graduation plate.

This is the most simple way of level measurement and indication is

quite visible from distance. The measurement is conducted without

any springs and tapes that offers high durability for long time opera-

tion.
