Industrial applications starting from oil refineries to vending machines require precision measurements of temperature, pressure, and flow to control complex and simple processes.
Within the food industry, for example, the accurate control of flow when filling bottles and cans can directly influence profits. Likewise, custody transfer applications, such as the exchange of raw and refined petroleum between tanks and tankers in the oil industry, require high-accuracy measurements.
Sino-Inst is a reliable source of various high accuracy flow meter solutions across different mediums of flow measurements.
High Accuracy Flow Meter: what does it mean?
Flow meter accuracy refers to how close the measured value is to the actual value. In flow meters, high accuracy means how close the output of the meter is to its calibration curve.
This is expressed as a percentage, e.g. ±1%. It means that any given reading can be in error 1% above or below the calibration curve.
In general, it can be said; that the lower the percentage, the more accurate your flow meter. These meters are typically used in applications where even minor errors in flow measurement could lead to significant issues.
Varieties of High Accuracy Flow Meters
Fundamental Varieties of High Accuracy Liquid Flow Meters:
Coriolis Flow Meters: A gold standard for liquid flow measurement i.e; Coriolis Flow Meters. It offers extraordinary accuracy. Can be up to 0.1%, 0.2%. A vibrating tube experiences a phase shift as liquid flows through it. This is exactly known as the Coriolis effect.
Electromagnetic Flow Meters: For measuring conductive liquids like water, slurry, and chemicals, Electromagnetic Flow Meters are the ideal solution. The measurement accuracy can reach 0.5%. They function by applying a magnetic field to the flow stream and measuring the voltage generated as the liquid moves through the field.
Liquid turbine flowmeter: Under the action of fluid, the impeller rotates under force, and its speed is proportional to the average flow velocity in the pipeline. Generally, it can reach ±1%R, ±0.5%R, and the high-precision type can reach ±0.2%R.
Gear Flow Meters: The cylindrical gear transmitter is processed with high precision and precisely installed. The rotation of the gear is scanned contactlessly, and each tooth generates a pulse with very high resolution. The cylindrical gear transmitter can measure very small flow rates and quantitatively measure small volumes of liquid. The accuracy can reach 0.5%.
Ultrasonic Flow Meters: Ultrasonic Flow Meters use sound waves to measure the flow rate of liquids. The measurement accuracy can reach 1%. They are non-invasive and can be used for both high-accuracy measurements and large-diameter pipes.
Applications of High-Accuracy Liquid Flow Meters
- Chemical and pharmaceutical industries for accurate dosing and mixing.
- Oil and gas refineries for pipeline measurement and quality control.
- Water treatment plants for flow measurement to fulfill regulatory protocol.
- Food and beverage production for ensuring consistent ingredient flow.
High Accuracy Gas Flow Meter
Varieties of High-Accuracy Gas Flow Meters
Coriolis Mass Flow Meters: These meters are capable of measuring both mass flow and density, making them fit for a variety of gas types, including natural gas, nitrogen, and oxygen. Common accuracy 0.1%R.
Thermal Mass Flow Meters: Thermal mass flow meters are also widely used in gas flow measurement. These meters are ideal for measuring gases such as natural gas, compressed air, and oxygen. Common accuracy 1.5%R.
Vortex flowmeter: Vortex flowmeter is also called Karman vortex flowmeter. It can measure a variety of gases, including air, nitrogen, oxygen, carbon dioxide, hydrogen and natural gas. It also includes special gases such as hydrogen chloride and ammonia, providing high-precision flow control. Common accuracy 1.0%R, 1.5 %R.
