Most volumetric flow meters will actually measure the water flowing speed rather than the volume of water. A laminar flow element (LFE) inside the meter forces the gas into laminar (streamlined) flow. The volumetric flow transducer will sense fluid flowing across the primary element then sanctions the transmitter to create a running flow signal. This tool will calculate the flow velocity in any units from the specified volumetric flow rate of a substance flowing through a round duct or pipe of a chosen diameter.

Translating fluid velocity into volumetric flow is quite simple, following this equation: Volumetric flow sensors belong in the category of process sensors, and are often also referred to as flow meters. Description; DATI TECNICI; Add to wishlist; Print; Information request; Contact us! The flow rate refers to the speed at which a process fluid is moving through pipelines, orifices, or vessels at a given time. Click on this link if you need more information about a Flow meter. You can find more information on Gas Meter Types for Flow Measurement. 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. which controls the volumetric flow in the feed line. A laminar flow element (LFD) insdie the meter forces the gas into laminar (streamlined) flow. 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. Industrial Flow Measurement . A flow meter is a test device used to measure the flow rate of process fluids and gases in industrial plants and facilities. The mass and volumetric flowmeters of FMA-1600A Series use the principle of differential pressure within a laminar flow field to deterime the mass flow rate. Ultrasonic Flow Meter for Slurry Measurement. A sampling of volumetric flowmeters includes differential pressure, electromagnetic, vortex and swirl, and variable area (rotameters). Volumetric flow meters are those meters designed to measure volumetric flow which is the volume of a liquid or gas which passes per unit of time. 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. The following devices measure volumetric flow: positive displacement meters, turbine flow meters, orifice plates, Venturis, vortex meters, and Pitot tubes. Magnetic Flow Meters are volumetric flow meters. Magnetic, ultrasonic, turbine, and vortex flowmeters are prime examples, where the sensing elements (of each meter type) respond directly to fluid velocity. Volumetric flow sensors belong to the category of Process sensors and are often also referred to as Flow meters. Excluded here for reasons of space are turbine, target, ultrasonic and positive displacement 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 … Save these instructions. Integrated sensor, display, transmitter, valve assembly, 120/230 VAC power adapter with communications cable, and NIST-traceable calibration report supplied by the manufacturer.

Mag meter is ideal for wastewater applications, or any dirty liquid which is conductive or water based. We offer a wide product portfolio of gas and liquid flow meters for low flow rates. Sierra’s mass vortex flow meters can be specified to measure up to five process variables with one process connection: volumetric flow, mass flow, density, pressure, and temperature. Volumetric Fluid Flow Meter 308778ZAC EN For precise metering of plural component fluids or solvents (depending on model). When choosing flowmeters, one should consider such intangible factors as familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and mean time between failure history, etc., at the particular plant site. Mass flow is a dynamic mass per time unit measured in grams per minute (g/min). Accuracy over a wide flow range can be as good as ± 0.5% of flow rate or better. The latter is based on the principle of a spring-supported piston. Click here to download the comprehensive 290-page handbook now. The majority of flowmeter technologies operate on the principle of interpreting fluid flow based on the velocity of the fluid. These meters are no ordinary volumetric flow meters. Mag meters are based on Faraday‘s principle of induction. Output signal reed switch pulser version, display . When corrected for temperature or density, volumetric flowmeters can provide values for mass liquid flow rates. We know that selecting the right flow meter is the key to success while selecting the wrong one means nothing but trouble. For each new calculation a unique conversion scale will be generated for the range of volumetric flow rates and flow speeds for the diameter specified.

This directly or indirectly measures the volume of water that will pass through a particular location in a specified timeframe. Though nearly any unit of volume or unit of time can be used, we most commonly see volumetric flow measured as gallons per minute (gpm) for water and other liquids and cubic feet per minute (cfm) for air and other gases. Many traditional flow meter technologies respond to the volumetric flow rate of the moving fluid.
