Series OMA Oxygen Flow Meter

Flow includes Flow Transmitters, Flow Sensors, Flow meters, Sight Flow Indicators and Water Meters. Mass Flow meters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston. Flow meters indicate flow rate. The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or with switch output. The different designs of the flow meters have a variety of applications.

Tapered bore in-line indicators for flow rate. Ideal for high purity or corrosive liquid applications, gas and liquid applications, air samplers and medical applications. Flow meters are shipped assembled and ready for panel mounting.

The Series OMA Oxygen Flow Meter is made especially for medical applications and manually controlling flow from oxygen generators. Flow levels are kept stable by precision valve and knob adjustment. The low cost flow meter is made from durable clear acrylic plastic. They easy-to-read scale is hot stamped into the acrylic so it will not wear off. The ball float is highly visible against the light blue background. Readings are repeatable within ±4% full scale accuracy.
