Interesting Facts about Liquid Flow Meters and Sensors
Liquid Flow Meter
A liquid flow meter is a device, which is utilized to gauge the flow of a liquid. A liquid flow meter is also a useful device when it comes to gauge the volume of liquid that flows through the pipes. A liquid flow meter is commonly deployed in most of the industrial as well as domestic areas in order to deliver the accurate measurement of liquid flow. It can also provide assistance in identifying a leakage in the pipes. Fundamentally there are two broad categorizations of the liquid flow meters namely displacement water meter and the velocity water meter. An additional variety of liquid flow meter is compound meter. It is an innovative blend of both velocity and displacement meters. Moreover, there are further different variants of these two categories of liquid flow meters based on their different features and prices.
Liquid flow meters can measure liquid volume in either cubic feet or inches by using a totalizer, which vary according to its specifications. There are straight and circular registers, which show the readings. Each of these registers contain a sequences of numbers, which can be used to determine the usage of liquid quite conveniently. Every kind of liquid flow meter operates on the basis of a specific technique. Accurate measurements of the supply flow are obtained by deploying the liquid flow meters closer to the feed lines. The liquid stream is gauged precisely by the liquid flow meters and measured outcomes are transferred to the database or exhibited on the display area of the meter.
The velocity flow meter mainly calculates the speed and converts in into the process rates such as Gallons or Litres per minute of the liquid. The information gathered and received by a velocity flow meter may be converted into volume using a number of techniques. There are a wide range of velocity flow meters, which include propeller, ultrasonic, magnetic, multi-jet and turbine meters. Velocity flow meters are specifically the most effective type for the measurement of the flow rate of large water streams. For the similar reason, they have been utilized in large industrial settings and plants.
A further remarkable variant of the liquid flow meter is the positive displacement meter that calculates the liquid flow by comparing it to the capacity of chamber to hold the liquid. The total number of times the chamber is filled and emptied assists to analyze the flow of liquid. A positive displacement meter may utilize a piston mechanism to gauge and record the information. It is most suitable to calculate a lower liquid flow, which is why a positive displacement meter is mainly used for homes, hotels, apartments and office buildings.
Liquid Flow Sensors
Although there are now digital liquid flow meters in use that offer a greater magnitude of accuracy and effectiveness, analog liquid flow meter are still being used. However, digital liquid flow meters utilize a wide range of techniques in order to gauge and measure the flow of liquids. Among the most widely used digital liquid flow meter include the ones based on magnetic and ultrasonic sensors that can accurately measure the flow of liquids. In order to manage mass flow measurement in the process industries, the use of liquid flow sensors is extremely significant. The liquid flow sensors are used for gauging mass flow, flow velocity or a volumetric flow rate of a liquid. Accurate measurement of liquid flow and control products are the key to become successful in a particular field of work. With the rise in the needs of such products, there are certain fact that needs to be realized related to the type of liquid flow sensor, its functionality and its capability to deliver exact calculations.
Flow sensors can measure various liquids such as semiconductor processing fluids, light oils, fuels, inks and other transparent or translucent liquids. Viscosity plays an important role as a sensor will not work with liquids that are too dense. Because optical liquid flow sensors operate using an infrared light emitter that use the absorption or reflection of light to capture precise measurements of the fluid, the transparency of the liquid passing through is also important. For example, if the liquid absorbs all of the light from the emitter, then the flow sensor will not work. Hazardous chemicals can also pose a problem to the flow sensor as the chemicals can damage sensitive parts of the device such as the fittings or O-rings. Fortunately, there are alternative materials available that offer greater resistance to liquid types. Some other options available are brass, stainless steel or PTFE fittings that may be used in the sensor’s body depending on the liquid. Among the wide range of liquid flow meters, it will be more convenient to select one with a range of distinctive features such as strength and ability to endure climatic changes.
