BAMO 1900/1901/1903 low flow rate flowmeter is designed for direct reading flow indicators with an adjustment valve for low flow rates of liquids or gases. It is a type of variable area flowmeter where the diver (”float”) moves inside a conical measuring tube.
Inductive type: Only for metal float; Cable output; Supplied with 1 m long cable. Add an amplifier relay providing an appropriate power supply to the inductive contact.
For contact in ATEX version: the contact must be connected via an Intrinsic Safety relay (on request).
