The flow of liquids in pipelines plays an important role in industry and commerce. Under most circumstances it is essential to know whether or not there is a flow in a pipeline, and to act upon that knowledge. That is the reason for, and the function of, McDonnell & Miller Flow Switches. McDonnell & Miller Air Flow Switches sense air flow or no air flow by responding only to velocity of air movement. They provide a positive and economical way to detect change or loss of air flow velocity caused by closed damper or fan inlet, a loose fan wheel, a slipped or broken fanbelt, a dirty or clogged filter, or an overload on a fan motor switch.

Model 274A, 335A, 335P, 335T and 338E are pneumatic instruments. The consists of the product line of Pneumatic Transmitters and Indicating or Recording Controllers. All 274A, 335A, 335P, 335T and 338E models are designed to meet the most stringent and demanding requirements for Oil & Gas Production, U.S. Navy Shipboard, and Process Plant applications.
The heart of the DP-driven instruments is the rugged Differential Pressure Unit (DPU) – featuring a time-proven liquid-filled bellows and torque tube design. Recording
and Controlling models are also available with Pressure or Temperature actuators.
Pneumatic Transmitters (Standard DP and Linear-with-Flow)
• Models 274A – DP Transmitters
• Actuated by ’s M199
• Rugged, Weatherproof, Non-corrosive Case
• Continuous Purging (pilot valve and nozzle exhaust inside)
• Operation Span Continuously Adjustable (100 – 20%)
• Adjustable Suppression (up to 80% of range)
• Large Valve Relays (no need for secondary booster)
• Span Continuously Adjustable (down to 20% of range)
• Air Consumption (at balance condition) 0.05 scfm max.
® Pneumatic Transmitters are actuated by the M199
Differential Pressure Unit (DPU) which is also available in a
NACE certified version.
® Pneumatic Transmitters are housed in a rugged, weatherproof case especially suited for use in corrosive fume environments. Since the pilot valve and nozzle exhaust
inside the case, continuous purging is achieved.
Changes in DP are transmitted mechanically to the flapper, which covers a small constant-feed nozzle. Any change in the position of the flapper will instantly change the nozzle pressure, which in turn controls the action of the 2-valve balanced relay to increase or decrease the output air pressure. A calibrated bellows assembly actuated by the output pressure serves to reposition the flapper mechanism and restore a state of equilibrium – in this manner, output air pressure varies in direct relation to the differential pressure applied to the instrument, or in direct proportion to the flow-rate. The relay is not affected by changes in output pressure and this makes it possible to maintain practically constant nozzle pressure at any output pressure.
Operating Span/Suppression (Linear-with-DP units only)
The operating span is continuously adjustable from 100- 20% of the DP range. Thus a unit with a differential pressure range of 0-100″ w.c. can be adjusted to provide a 3-15 PSI (207 mbar-1 bar) output signal (direct or reverse) for any span from 0-20″ w.c. to 0-100″ w.c. (0-50 mbar to 0-248 mbar) range. The operating span can be shifted anywhere within the range of the differential pressure unit

The Model 351, 352 and 353 Liquid Level System provides accurate hydraulic transmission of a process medium for measuring the level of liquids contained in a process vessel. The self-contained system of the 351, 352 and 353 models is typically mounted outside the vessel. Floats, levers, pins, and other mechanical devices susceptible to contamination or wear are not required. Because the basic system is actuated by the process media, local indication is possible without external power. Liquid Level Sensors can be purchased as a component of a factorybuilt system, or as a part for a field-installed system. Sealed sensor systems can be designed in the following configurations:
• a single sensor system ( Model 351)
• a dual-sensor system ( Model 352)
Model 351 Liquid Level System
The Model 351 consists of a single reference sensor connected by capillary tubing to a Differential Pressure Unit (DPU). Hydraulic fluid is sealed inside the sensor and the capillary tubing, eliminating the need for additional piping.
Model 352 Liquid Level System
The Model 352 consists of two reference sensors connected by capillary tubing to a DPU.
For applications involving corrosive fluids or tank temperatures above 200°F (95°C), a dual-sensor configuration is recommended. For applications involving unusual fill requirements due to liquid volumes or high ambient temperatures, a Model 353 system is recommended. The Model 353 system can be designed with one or two sensors.

The Model 247 bellows within the DPU move in response to changes in the differential pressure measured at the primary device installed in the process system. Movement of the bellows of the model 247 is mechanically transferred to the indicator mechanism which in turn positions the indicator pointer.
Changes in pressure within the Differential Pressure Unit pressure housings cause the DPU bellows of the model 2477 to move in the direction of the decreasing pressure. Movement of the bellows of de 247 model is transferred to the DPU torque tuube output shaft. The Torque tube shaft is the mechanical output of the DPU which is attached to the back of the indicator case. The torque tube shaft is connected to the indicator mechanism.
The DPU torque tube shaft is connected to the drive arm of the indicator mechanism. The torque tube shaft rotates in response to DPU bellows movement and this rotation is mechanically transmitted through the drive arm and associated mechnism to position the pointer on the scale to the indication relative to the differential pressure measured by the DPU.
