Velocity-based flow meters such as magnetic, vortex, turbine, ultrasonic, and optical generate output signals proportional to the speed of fluid molecules and nothing else. Volumetric flow sensors belong to the category of Process sensors and are often also referred to as Flow meters. The flow (Q) is equal to the cross-sectional area of the pipe (A) in a volumetric flow meter, and the velocity of the flowing fluid (v): Q = A * v. The mass flow can be expressed in a mass flow meter as follows: ṁ = Q ∗ρ (where Q is the volumetric flow rate and ρ … A flow meter (or flow sensor) is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. Magnetic, ultrasonic, turbine, and vortex flowmeters are prime examples, where the sensing elements (of each meter type) respond directly to fluid velocity.

The following devices measure volumetric flow: positive displacement meters, turbine flow meters, orifice plates, Venturis, vortex meters, and Pitot tubes. A laminar flow element (LFD) insdie the meter forces the gas into laminar (streamlined) flow. A flow meter has a primary element, transmitter, and transducer. When corrected for temperature or density, volumetric flowmeters can provide values for mass liquid flow rates. MX-F Volumetric flow meters oval gears. Most Alicat gas flow instruments provide readings for both mass flow and volumetric flow, so users can use the measure that makes the most sense for each application. Many traditional flow meter technologies respond to the volumetric flow rate of the moving fluid. This directly or indirectly measures the volume of water that will pass through a particular location in a specified timeframe. Ultrasonic Flow Meter for Slurry Measurement.

Go back; Measuring principle oval gears Measuring range 0.008÷1,200 lt/min as a function of the diameter . Alicat’s gas flow controllers allow for closed loop control of either mass flow rate or volumetric flow rate. We know that selecting the right flow meter is the key to success while selecting the wrong one means nothing but trouble. Most volumetric flow meters will actually measure the water flowing speed rather than the volume of water. Flow through a large penstock such as used at a hydroelectric power plant can be measured by averaging the flow velocity over the entire area. You can find more information on Gas Meter Types for Flow Measurement. Here not the divisor 3,6 is used but 3.600, because cubic meters remain and are not converted into liters (1 hour = 3600 seconds). Excluded here for reasons of space are turbine, target, ultrasonic and positive displacement meters. A sampling of volumetric flowmeters includes differential pressure, electromagnetic, vortex and swirl, and variable area (rotameters). Volumetric flow meter basically measures the water, vapor or gas amounts flowing through a pipe in a particular timeframe. Translating fluid velocity into volumetric flow is quite simple, following this equation: The flow velocity is to be calculated in m³/s. Magnetic-inductive volumetric flow meters and Mechatronic volumetric flow sensors can be distinguished. Propeller-type current meters (similar to the purely mechanical Ekman current meter, but now with electronic data acquisition) can be traversed over the area of the penstock and velocities averaged to calculate total flow. First, we convert the volumetric flow rate from m³/h to m³/s, since the final result of the flow velocity is to be given in m/s. A laminar flow element (LFD) insdie the meter forces the gas into laminar (streamlined) flow. These meters are no ordinary volumetric flow meters. Mass flow is a dynamic mass per time unit measured in grams per minute (g/min). qui commande le débit volumique dans la conduite d'arrivée.
