Differential Pressure Units (DPU)
Showing all 11 results
The basic theory behind Barton differential pressure units (DPU) is that the pressure decrease around the meter is equal to the flow rate square. For calculating this pressure difference, multiple pressure sensors covered earlier in the chapter are used. In order to create a pressure differential, the mechanical component of the sensor is used while the sensor’s electrical part calculates the pressure difference.

Barton 226 dp indicator
The Model 226 Differential Pressure (DP) Indicator is used to measure the amount of liquid flow or fluid. The indicator has a dial of 3 inches with a 270 ° key range. The tool is linked to the low-and high-pressure ends of a main unit situated in the system queue for stream readings. The main unit can be any pressure drop tool such as an orifice plate, venturi pipe, or stream pipe. For liquid concentration readings, the tool is linked to monitor alterations in hydrostatic pressure induced by fluid height differences in a ship. The D.P. motion. Indicator has null and period adjustment micrometer screws. These modifications can be made without withdrawing the scale screen or the signaling pointer.
In applications where weight and room are at a cost, the ITT Barton Model M226C is used. Widespread use in jet engine and rocket test programs, ground support equipment for aircraft, water
Barton 224 dp unit
The Barton Model 224 Differential Pressure Unit (DPU) is a mechanical device that monitors the parallel differential stress of a gas or liquid passing through a process system or the quantity of liquid stored in a process tank. In the factory-stream measurement process scheme, the DPU is linked to a main unit (e.g., venturi, orifice screen, or flow tube). For liquid concentration readings, the DPU can be linked in a multitude of respects to assess the range of stress induced by fluid density differences in the unit ship.
The Barton Model 224 DPU is accessible in separate stress scores to evaluate particular distances between 0-30 inches of water column and 0-1000 psi, with secure work stress (SWP) outcomes of 500 to 10,000 psi (224 Non-C restricted to 500 to 3,000 psi SWP). Table 1-1, point 4. The 224C Bellows Unit Assembly (BUA) is manufactured in three bellow sizes: 1-5/8 inch, 5/8
Barton 752 Differential Pressure Transmitter
The Model 752 Differential Pressure Transmitters provide a 4-20 mA or 10-50 mA signal equal to the differential stress and transmit it to different capturing, monitoring or viewing devices. Sources of differential stress include liquid temperature and particular ship gravity changes; flux of liquids and gasses through orifice pipes, nozzles or venturis; pressure drop across filters and static line conditions, etc.
The Model 752 receivers merge an electronic circuit with a differential stress device (DPU). Production of 4-20 mA or 10-50 mA is compatible with a wide range of digital collection, energy and teaching equipment. The tool uses miniaturized hybrid electronic circuits and a cantilever beam of detection of molecular-bonded strain gage, driven directly by the movement of the bellows within the DPU. In many applications, the electrical connections are located within a junction box.

Barton 351 Liquid Level Systems
The Model 351 comprises of a single input sensor linked to a Barton Differential Pressure Unit (DPU) by capillary tubing. Hydraulic fluid is sealed inside the sensor and capillary tube, eliminating the need for additional piping. As shipped from the factory, the Model 351 system only needs to be mounted on the vessel to provide continuous level measurement when used with a Barton read instrument.
The sensor can be mounted in vented or closed system ships. The readout instrument (DPU, for example) can be installed at different elevations (i.e. below the vessel, at the upper connection of the vessel or above the vessel) as long as the instrument calibration considers the difference in elevation between the instrument and the sensor. Depending on the stress score needed, a Model 351 or Model 352 scheme can include any of three device kinds: 500-psi SWP sensor, 3,000-psi SWP sensor, No-pressure ranking sensor. All three
