Construction of Universal motor. Construction of a universal motor is very similar to the construction of a DC machine. It consists of a stator on which field poles are mounted. Field coils are wound on the field poles. However, the whole magnetic path (stator field circuit and also armature) is laminated.
Since in a variable orifice flow meter there is a mixture of turbulent and laminar flow, for calibration purposes both density and viscosity of the gas are important. Consequently, careful calibration is required if a flow meter is used for a different gas than that for which it was designed. When the anaesthesia machines are used at high altitudes since the density of the gases decreases, when higher flows are .
The conventional fluted meter roller (on the right) is available through service parts. It can apply rates up to and greater than g (8 oz) per m (1000 ft). Of the two meter rollers, the cupped roller will cover about 95 percent of producer chemical application needs.
Mar 15, 2011· A Venturi Meter is a device that allows flow rates through pipes to be calculated by measuring the difference in pressure created by a contraction in a pipe. When the flow goes through the contraction it must speed up, and so the pressure must drop. By measuring the two pressures, engineers can directly calculate the velocity of the fluid.
Canalta fabricates custom meter runs for all of our orifice fitting models and a variety of other metering applications. Whether the size is 2" or 30", high or low pressure, wet, dry or corrosive service, we can put together a custom meter run package that meets your specification or performance needs and perfectly matches your Canalta Orifice Fitting or other specialized metering device.
Industrial flow meters/flow transmitters Introduction Flow meters are an integral tool for measuring the flow of liquid, gas, or a mixture of both in applications used in ... key factors for determining the right flow meter for a particular application. Additional considerations such as ... Differentialpressure orifice flow meter.

Referring now to FIG. 1, therein is shown a pump 10 having a pump casing 11, an impeller 12, an impeller drive shaft 13 which is connected to a drive motor (not shown), a cutwater 14, a casing volute 15, a discharge nozzle 9, a pump discharge outlet 16 and a pump outlet attachment flange 17 to which is attached an integral orifice plate 2.
Apr 21, 2018· Both PFD (Process Flow Diagram) and PID (Piping/Process Instrumentation Diagram) are chemical / process engineering drawings. These drawings are very useful as they convey the right amount of process information as needed during various stages of bidding, engineering design, procurement, construction, operating commissioning phases of the process.
A Coriolis meter is based on the principles of motion mechanics. When the process fluid enters the sensor, it is split. During operation, a drive coil stimulates the tubes to oscillate in opposition at the natural resonant frequency. As the tubes oscillate, the voltage generated from .
Inspection and Test Plan. The ITP have a tabular format and the content extracted from the construction code. In each row of the table, there is a quality control and inspection requirement and this determines which party is responsible for control and inspection. There .
CONSTRUCTION OF VENTURI METER IN ENGINEERING. ABSTRACT. The project was on the construction of a Venturi meter. Venturi meter being a measuring instruction was used in determining the flow rate of fluid down a pipe or the rate of discharge in a pipeline and is often fixed permanently at different sections of the piple line to know the discharge there.
Builtin values for orifice discharge coefficients. Equations. From Dally et al. (1993) and Streeter et al. (1985) The tank discharge equations are valid for: H > m ( ft) and B > cm (1 inch). Values will be computed even if H or B is too small, but a warning message will appear. where: A = orifice area,...
requirements for the construction of orifice meter tubes, as defined in this publication, will be discussed in greater detail throughout this paper. Definition of Terms Primary Element – Defined as the orifice plate, the orifice plate holder with associated differential pressure sensing taps, the meter tube, and flow conditioner if used.
Because of this, mechanical linkage is needed to multiply the weight of the float, and the orifice diameter on air release valves is limited in size to reduce the breaking force needed. Air/Vacuum Valves. An air/vacuum valve has a fullsize orifice ranging from half an inch to 20 inches. Because of this, the valves can exhaust large volumes of air.
