Flowmeters

The flowmeters type SF1, SF2 and SF3 are devices for the supply of medical

gases with one (SF1), two (SF2) or three (SF3) antistatic and graduated measure tubes

and complete with a dosage unit. The body is made of anodized aluminum and the inlet

connections for O2 and N2O and Air at the bottom of the flowmeter are arranged to be

connected to the centralized gases feeding system or to the cylinders complete with pressure

regulators. At the outlet of the dosage unit, an anaesthesia evaporator can be connected or the

gas mixture can be supplied directly through the gas feeding unit.

Different constructions can be made on request.

 

The flowmeters type FM2200, FM2300, FM2500 and FM2800 are

devices for the supply of medical gases with two antistatic and graduated measure tubes

and completewith a dosage unit. The body is made of anodized aluminum and the inlet connections

for O2 and N2O at the bottom of the flowmeter are arranged to be connected to the centralized

gases feeding system or to the cylinders complete with pressure regulators. The gas feeding units

includes a valve that automatically blocks the N2O supply when the feeding pressure of O2 drops

approximately below the value of 0,8 bar. The mixtures of O2 - N2O can be supplied through a

dosage unit. An incorporated mixing device proportions the N2O in such a way

that a minimum quantity of at least 30% O2 is always present in the gas mixture.

At the outlet of the dosage unit, an anaesthesia evaporator can be connected or the gas mixture can

be supplied directly through the gas feeding unit. The button O2 +, when foreseen, can be used for

a quick supply of O2 directly at the outlet of the mixture on the gas feeding unit.
