A meter's performance can be determined by its turndown ratio. Turndown ratio is the effective dynamic or operating range of the flow meter. For example, if a 500 SCCM flow rate device has a turndown ratio of 50:1; it will operate effectively and resolve flow down to 10 SCCM. If the same device has a turndown of 100:1, then it will resolve effectively to 5 SCCM.

Differential Pressure Meters
|
|
|
| |
Your choices are...
|
|
|
| |
Cone Type
|
|
Cone-type devices place a cone directly in the center of the fluid flow to create differential pressure (DP) that can be measured before and after the obstruction. DP is proportional to velocity.
|
| |
Elbow Tap Meter
|
|
Elbow tap meters operate on the principle that when liquid travels in a circular path, centrifugal force is exerted along the outer edges. When a liquid flows through a pipe elbow, the force on the elbow's interior surface is proportional to the density of the liquid times the square of its velocity. Typically, the device consists of a 45-degree pipe elbow in fluid flow, with high-pressure tap outside of the elbow and low-pressure tap inside of the elbow.
|
| |
Flow Nozzle
|
|
Flow nozzles are similar to Venturi tubes, but the nozzle opening is an elliptical restriction in the flow. There is no outlet area for pressure recovery and pressure loss is comparable to an orifice plate. Flow nozzles can handle both clean and dirty fluids; however, viscosity can pose a problem through a constricted orifice.
|
| |
Laminar Flow
|
|
Laminar flow elements have a constriction that consists of a tube bundle or parallel plates. They are used to measure flows with low Reynolds numbers. The differential pressure across this type of flow meter is linear with the flow.
|
| |
Orifice Plate
|
|
Orifice plates are simple and cost-effective flat pieces of metal with a specific-sized, bored-in hole. They constrict the flow of a fluid to produce a differential pressure (DP) across the plate. Orifice plates tend to have a higher-pressure loss than other DP meters, but can handle both clean and dirty fluids. Viscosity can be problematic through a constricted orifice.
|
| |
Pitot Tube
|
|
Pitot tubes measure the difference between total and static pressure. To determine the total pressure, a hole in the flow path is pressurized by both the flow pressure and the surrounding static pressure. A hole that is perpendicular to the flow is pressurized by static pressure alone. A transducer is used to measure the difference between the total pressure and the static pressure. When the pressure difference is determined and the local values for pressure and temperature are known, Bernoulli's equation can be used to derive the velocity.
|
| |
Rotameter
|
|
Rotameters (variable area flow meters) consist of a tapered glass tube that is vertically-positioned in the fluid flow with a float. When there is no liquid flow, the float rests freely at the bottom of the tube. As liquid enters the bottom of the tube, the float begins to rise in relation to the amount of flow.
|
| |
Target Meter
|
|
Target meters have a physical target located directly in the fluid flow. The pressure caused by the flow hitting the target causes the target to deflect. The deflection of the target is measured by an instrument. Target flow meters can be used for any type of liquid, gas, or steam cryogenics.
|
| |
Vane Style - Variable Area
|
|
Vane-style variable-area flow meters have a spring-opposed vane that moves in relation to the flow rate. Similarly, piston variable-area flow meters use a spring-opposed piston that moves in relation to the flow rate. These flow meters can be connected to an indicator or transmitter.
|
| |
Venturi Tube
|
|
Venturi tubes operate by gradually narrowing the diameter of the flow pipe and measuring the resultant drop in pressure. They can handle clean and dirty fluids, although the constricted orifice design can have problems with viscous media.

|
| |

|
|
Oval-gear meters have two rotating, oval-shaped gears with synchronized, close-fitting teeth. A fixed quantity of liquid passes through the meter for each revolution. Shaft rotation can be monitored to obtain specific flow rates.

Electromagnetic Meter
|
|
Electromagnetic flow meters operate on Faraday's law of electromagnetic induction, which states that a voltage is induced when a conductor moves through a magnetic field. The liquid serves as the conductor; the magnetic field is created by energized coils outside the flow tube.
|
| |
Paddlewheel
|
|
Paddlewheel flow meters have a paddlewheel that is inserted directly into the flow of fluid. The paddlewheel rotates freely, proportional to the fluid flow. Magnetic pick-ups are used to produce a waveform signal which is converted to an appropriate output. Paddlewheel flow meters must be mounted in a straight run of pipe. They do not offer a high degree of accuracy, but are low cost alternatives for viscous applications.
|
| |
Sonar
|
|
Sonar is used to measure the volumetric flow-rate of a process fluid. The measurement principle involves characterizing the speed at which coherent vortical structures flow past an array of pressure-based or strain-based sensors which are mounted axially, along the pipe.
|
| |
Turbine Meter
|
|
Turbine meters use a pipe-mounted rotor that is perpendicular to the liquid flow. The rotor spins as the medium passes through the blades. The rotational speed is a direct function of the flow rate and can be sensed by magnetic pick-up, photoelectric cell, or gears.
|
| |
Ultrasonic Meter
|
|
Ultrasonic meters include Doppler Effect meters and time of flight meters. Doppler meters measure the frequency shifts caused by liquid flow. The frequency shift is proportional to the liquid's velocity. Time of flight meters use the speed of the signal traveling between two transducers. This speed increases or decreases with the direction of transmission and the velocity of the liquid being measured. Time of flight meters do not work well with liquids with suspended solids or air gaps.
|
| |
Vortex (Shedding) Meter
|
|
With vortex (shedding) meters, the frequency of vortices shed from a bluff body placed in the flow stream is proportional to material velocity.

With Coriolis meters, fluid is passed through a small vibrating flow tube. The resulting deflection of the flow tube is proportional to the mass flow rate of material
