McDonnell & Miller Flow Switches now on stock!

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.

ITT Barton Model 274A, 335A, 335P, 335T and 338E

ITT Barton 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 ITT Barton 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 ITT Barton 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 Barton’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.

Actuating Units:
Barton® Pneumatic Transmitters are actuated by the M199
Differential Pressure Unit (DPU) which is also available in a
NACE certified version.

Cases
:
Barton® 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.

Transmitting Unit:
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

ITT Barton Model 247

The Barton 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 Barton 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 Barton model 2477 to move in the direction of the decreasing pressure. Movement of the bellows of de Barton 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.

ITT Barton Model 224

The Barton Model 224/224C Differential Pressure Unit (DPU) is a mechanical device that measures differential pressure relative to a gas or liquid flowing through a process system, or to the level of a liquid contained in a process vessel. For process flow measurements, the DPU is connected across a primary device (e.g., venturi, orifice plate, or flow tube) located in the process system. For liquid level measurements, the DPU may be connected in a variety of ways to measure the difference in pressure caused by variations in the level of the liquid in the process vessel.

Product Description
The Model 224/224C DPU is a dual bellows assembly enclosed within pressure housings. The dual bellows assembly consists of two opposing internally connected liquid-filled bellows, a center-block, range springs, overrange valves, and a torque tube assembly.
The pressure housings are connected by pipe or tubing to the primary device located in the system piping. Variations in differential pressure within the pressure housings cause the bellows to expand or contract in a linear direction towards the side having the lowest pressure. The linear movement of the bellows is converted into angular rotation when
transmitted to the torque tube shaft by the drive arm and this mechanical motion
actuates the mechanism of the process monitoring instrument. The process monitoring instrument that is connected to the torque tube assembly may be an indicator, a switch, a transmitter, a recorder, or other process control device.

Specifications
The Model 224/224C DPU is available in various pressure ratings to measure to specific ranges between 0-30 inches of water column and 0-1000 psi, with safe working pressure (SWP) ratings from 500 to 10,000 psi (224 Non-C limited to 500 to 3,000 psi SWP). See Table 1-1, page 4. The 224C Bellows Unit Assembly (BUA) is produced in three bellows sizes: 1- 5/8 inch, 5/8 inch, and 3/4 inch diameter. The 1-5/8 inch diameter BUA accommodates differential pressures to 55 psi. The range springs of this BUA are contained within the bellows and do not come in contact with the measured liquid. The 3/4 inch BUA accommodates differential pressures up to 400 psi and the 5/8 inch BUA up to 1,000 psi. The range springs of these BUAs are grouped around the outside of the bellows.

Barton Instruments Model 322C Blind Switch

Model 322C Blind Switch

The Model 322C is a blind SPDT,
snap-acting switch designed
for use in hazardous areas. An
optional two-switch configuration
is available. The Model 322C
provides a highly repeatable alarm
signal capable of performing electrically controlled system
functions for liquid level and flow applications.
Switch
The switch is adjustable to open (normally closed) or close
(normally open) on either increasing or decreasing DP and
is positively locked to prevent drift. Switch adjustments are
accessible when the cover is removed.
• AC Rating:
• 5 amps @125V
• 2.5 amps @240V
• DC Rating:
• (Inductive) 2.5 amps @30V
• (Resistive) 4.0 amps @30V
• Actuated by the 224 DPU
Operation
For flow applications, the unit is connected by tubing to
the LP and HP sides of the primary device (orifice plate,
venturi, or flow tube) in the process run. For liquid level,
the DPU is connected to measure the variations in DP
produced when the liquid level varies. These changes are
used to control the switch function.
The electrical alarm or control unit circuit is connected to
the switch (mounted on the DPU). Movement of the DPU
shaft actuates the switch mechanism when the DP reaches
a pre-set level.

Barton Instruments Indicating Transmitter Switch (ITS)

Barton Instruments Series Indicating-Transmitter Switch

Barton Instruments ITS Series DP Indicating-Transmitter Switches provide local indication
(process driven), 2- or 4-switch, and 2-wire 4-20 mA output.

• Measures relatively low DP at high static pressures
• 4-20 mA output (linear with pointer)
• SPDT or DPDT switch operation
• Switches adjusted over entire scale
• Switch backup battery for failsafe
• Output calibration jacks
• Non-contact pointer position detection
• Remote low-battery indication
• Retrofits Barton 6-inch switch case using existing DPU
• Actuated by the 224 DPU

Application

Typical applications include on-off pump control, liquid level, pressure drop across a filter, flow alarms, and absolute pressure measurement, indicating, switching, and
transmitting.

Operation

Switch contacts adjustable over the entire scale. Setpoints are adjustable with a control screw, without calibration equipment. Pointer movement is directly coupled to a precision potentiometer that produces an electrical signal that drives a linear 4-20 mA output and
the switches. Switches can be set for high or low, or both (with two contacts). Jumpers can be set to operate two switches together for DPDT or on/off control between two set-points.
