Industrial gear flow meters are designed for a variety of chemical applications including petroleum based fluids, water solutions and any other liquid compatible with the materials of construction. Working Principal Turbine meters are inferential measurement devices that measure a flow rate indirectly by using the natural kinetic energy of the flow as it passes through the angled blades of the turbine rotor. Power is the rate of doing work. 1 Definition of Piping Pipe is a pressure tight cylinder used to convey a fluid or to transmit a fluid pressure, ordinarily designated pipe in applicable material specifications. 1m head of water = 9810 Pa (100m of head is almost 7 times of atmospheric. The translation from Greek is straightforward: "anem-" being the root of "wind" and "meter" meaning (in general terms, not as a quantity) "measure. Just like every other equipment, DP transmitters can malfunction while in service. Turbine flow meters use the mechanical energy of the liquid to rotate a rotor in the flow stream. The Doppler shit method. The energy in the wind turns two or three propeller-like blades around a rotor. Highprecision RTDs - of Pt-100 type (class 1/10 DIN, 0. 8 Differential Devices with a Flow Measurement Mechanism in the Bypass 167 8. When fluid flow through the venture meter then pressure difference is created which measured by the differential manometer. Turbine engines power many of today's aircraft. With magnetic sensors, the rotation of the turbine generates a “pulse” which is picked up by a sensor. Francis turbine is a combination of impulse & reaction turbine. Thus, the signals from the wild stream process variable, PVw, and the controlled stream process variable, PVc, should increase and decrease in a straight-line fashion as the individual flow rates increase and decrease. Water pressure decreases as it passes through the turbine imparting reaction on the turbine blades making the turbine rotate.

Explore Underwater Turbines with Free Download of Seminar Report and PPT in PDF and DOC Format. Since this differential pressure is in direct proportion to the flow-rate as per the Bernoulli's Equation hence the differential pressure instrument can be configured to display flow-rate instead of showing differential pressure. Ultrasonics flowmeters will generally not work with distilled water or drinking water. Just like every other equipment, DP transmitters can malfunction while in service. Velocity meters are good for high flow applications. More commonly, a venturi can use this negative pressure to draw a second fluid into the primary flow. 9270 Old Katy Rd, Houston, Texas 77055 ABSTRACT This paper discusses fundamental issues relative to ultrasonic gas flow meters used for measurement of natural gas.

Gas turbine engines derive their power from burning fuel in a combustion chamber and using the fast flowing combustion gases to drive a turbine in much the same way as the high pressure steam drives a steam turbine. Abrupt transitions from gas flow to liquid flow should be avoided because they can mechanically stress the flowmeter, degrade accuracy, and/or damage the flowmeter. 5 Integral Orifice Meters 163 8. 11 Pipework Features - Bend or Elbow Used as a Meter 169. To explain how a force transducer works, we first have to answer the question: how does a strain gauge (or SG) work? For most common force transducers have strain gauges inside them. In industrial applications, pitot tubes are used to measure air flow in pipes, ducts, and stacks, and liquid flow in pipes, weirs, and open channels. The difference lies on the rotating elements; they could be gear, lobe, vane, or screw. For example, 10 PD means place the fl ow meter ten times its inside diameter away from the source of turbulence. The unit of flow in North America, at least in the pump industry, is the US gallon per minute, USgpm. Thus, two levels of inference (basic assumptions) are necessary to obtain volumetric flow rate from a turbine meter. First Assumption.
