Series MTF Multitube Flow System

Customize to Fit Application, 65 mm or 150 mm Variable Area Flow Tubes

Customize flow systems to meet application requirements. Systems can be configured with up to six different flow tubes with various flow capacities and flow patterns. The Series MTF Multitube Flow Systems are ideal for multichannel metering, mixing, or monitoring applications.

To Customize your flow system:

Determine the flow pattern required for the application.
Select a 65 mm or 150 mm frame, along with the appropriate number of tubes required, flow pattern, and wetted parts. Choose a 150 mm Gas Proportioner Frame (Series MTP) to blend the 2 or 3 gases at required concentrations. Gas proportioner frames are typically used at 50 psi.
Choose the appropriate 65 mm or 150 mm correlated flow tubes, for air or water.
Select a valve cartridge if desired that matches the range of the flow tube.

Series OMA Oxygen Flowmeter

Use to Indicate and Manually Control Oxygen Flow

Series OMA Oxygen Flowmeter (OMA-1 & OMA-2)

Use to Indicate and Manually Control Oxygen Flow (4-37/64" high)

Series OMA Oxygen Flowmeter (OMA-3 & OMA-4)

The Compact Series OMA Oxygen Flowmeter 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 flowmeter 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.

KA Regulator Kits

Optional extras for both Rate-Master® Flowmeters and Visi-Float® Flowmeters

Regulator Kits are available as optional extras for both Rate-Master® Flowmeters and Visi-Float® Flowmeters models. This view shows Model VFA Visi-Float® flowmeter with integrally connected constant differential pressure regulator. Recommended for use where inlet air pressure fluctuates widely and constant flow is required.

The regulator maintains a constant pressure differential of approximately 3 ± .15 psig. Supply pressure must be at least 3 psig above the flowmeter discharge to operate. The standard regulator may be used with any Dwyer Series RM or VF flowmeter up to 200 scfh. For higher flow rates consult the factory.
