What is difference between flow rate and flow velocity in flow tubes?
velocity is the speed of the flow (for example, meters/sec.) Flow rate is the volume per unit time (example: liters/sec.)
Why does plastic flow occur only 50 meters below ice?
It takes the weight of that much ice to cause the plastic flow.
Why does plastic flow occur only below 50 meters of ice?
It takes the weight of that much ice to cause the plastic flow.
How accurate are different types of flow meters in measuring FEV1?
Generally, most flow meters are very accurate in FEV1. However, device accuracy is not especially important, rather it is essential that you take multiple measurements to calculate an accurate working average.
What is the dimension of the flow rate?
This question is not specific enough to answer. If we knew which type of flow rate you were speaking of we could answer this. For example there is a volumetric flow rate which is the volume of fluid that passes through any given surface per unit time.
What are disruptive flow meters?
include magnetic flow meters and ultrasonic flow meters.
What are flow meters used for?
Flow meters are used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or gas.
What type of revenue do flow meters generate?
Flow meters have historically constituted one of the largest sources of industry revenue.
What flow meter products are offered by Hedland?
Flow meter products offered by Hedland include High Pressure Flow Meters and Turbine Flow Meters. Hedland also offers Pressure Indicators, Variable E-Z View Meters and Ultra Sonic Transit Time.
Where can one purchase a peak flow meter?
There are many places to purchase peak flow meters. Peak flow meters are used for asthma patients and can usually be found locally at a drugstore or mass retailer.
How do you select the right flow meter for your application?
Flow meter categories based on fluid Some flow meters can be easily eliminated because they simply will not work with the application. For instance, electromagnetic flow meters will not work with hydrocarbons and require a conductive liquid to function. Many flow meters cannot measure gases or slurries. Listed below are some of the main flow meter categories paired with the fluid type the meters can handle. Gas – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Area, Variable Differential Pressure, Positive Displacement, Turbine Liquid – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Differential Pressure, Positive Displacement, Turbine, Electromagnetic Slurry – Coriolis Mass, some subsets of Variable Differential Pressure, Electromagnetic, Ultrasonic Vapour – Vortex, Ultrasonic, Diaphragm, Floating Element
Where can one find a guide on reading a fuel flow meter?
You can find a guide on reading a fuel flow meter from sites with topics on flow metering or specifically fuel flow meters. The Flow Meter Directory is one such site. You can also use FloScan Australia which is a leading manufacturer of fuel flow meters.
Which are the different types of flow meters?
Differential Pressure Flow Meters – Refinery and oil and gas industries are largely dependent on differential pressure flow meters for their liquid flow measurement applications. Like many other flow meter equipment, this unit also contains a primary and a secondary element. The purpose of the primary element is to introduce a constriction in the pipe that contains liquid. As a result of this constriction, differential pressure is created in the pipe. The secondary element in the unit measures this pressure differential, and accordingly determines the fluid flow. The fluid flow rate is then displayed on the monitor.Differential pressure meters are available in several types. These include; orifices, venturi tubes, flow tubes, flow nozzles, elbow-tap meters, target meters, and variable-area meters. Application users must select the right type after analyzing the pipe’s size, flow conditions, and nature of liquids. Positive Displacement Flow Meters – This flow meter type offers unmatched service for measuring the flow of viscous liquids. It is brilliantly designed to directly measure the liquid flow as and when it passes through the flow meter. The unit entraps fluid when it is moving through the flow meter. This equipment is ideal to measure the flow of petrochemicals, adhesives, and paints.Some of the advantages associated with this unit include: high accuracy, low pressure drop, self-contained operation, low operating costs, and long service life. Positive displacement flow meters are largely utilized for precision flow meter applications in chemical, power, pharmaceutical, and food processing industries.There are several types of displacement flow meters available for industry specific applications. These include, reciprocating piston, oval gear, nutating disk, and rotary vane meters. Velocity Flow Meters – These types of flow meters are largely procured for applications in power generation, waste water treatment, chemical and refinery industries. They can be directly connected to pipelines to operate linearly with respect to the flow rate. Directly attached to pipelines, these units are supplied with flanges or fittings. Some of the advantages of these units include: fixed pressure loss at all flow rates, outstanding accuracy when used with low-viscous fluids, reliable operation over a wide range of pressures and temperatures.Velocity meters are available in several types. These include, turbine and paddle wheel, ultrasonic, electromagnetic, vortex-shedding, and Doppler ultra-sonic flow meters. Mass Flow Meters – When precise measurement of mass rate of a liquid is your requirement, then mass flow meters are the ideal solution. Unlike differential pressure meters, which measure volumetric flow, this unit measures the mass rate of the flow in a pipe. These flow meters are largely used for measuring liquids whose viscosities vary with velocity. Some of the advantages of these systems include: reliable operation over a wide range of pressures and temperatures, and extremely high accuracy.Mass flow meters are available in two types, namely, coriolis and thermal-type mass flow meters. Open Channel Meters – As the name implies, these types are ideal for measuring liquid flow in open channels. These units enable continuous and precise flow rate monitoring in tunnels, partially filled pipes, canals, streams, and rivers. Some of the advantages associated with these units include, versatile modular system, unparalleled accuracy, easy-to-install design.

What kind of tools do hydrologist use?
It depends on the type of work being done. Surface water hydrologists may use various devices to monitor the level and/or flow of water, such as flumes, weirs, flow meters, staff gauges, and pressure transducer/data loggers. Groundwater hydrologists often use depth meters, pressure transducers/data loggers, pumps, bailers, flow meters, generators, compressors, and so on. Both will use a wide array of water chemistry tools (pH meters, dissolved oxygen meters, electrical conductivity/salinity meters, field chemistry screening kits, and so on).
How does flow sensor equipment work?
The way a flow sensor works depends on the type of flow sensor. The simplest forms like mechanical flow meters use a pressure sensor to measure volume capacity and rate. Essentially a flow sensor measures the quantity of liquid by measuring force created by it's movement. They can do this either mechanically or electronically.
