Abstract: Huasheng Instrument--Displacement flow meter information is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. Huasheng Instruments--Positive Flowmeter Positive Displacement Flowmeter Positive displacement
flowmeter, also known as fixed displacement flowmeter, referred to as PD flowmeter, is the most accurate type of flowmeter. It uses mechanical measuring elements to continuously divide the fluid into individual knowns. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of Huasheng Instruments - Volumetric Flow Meters Huasheng Instrument - Positive Displacement Flowmeter Positive displacement flowmeter Positive displacement flowmeter, also known as fixed displacement flowmeter, referred to as PD flowmeter, is the most accurate type of flowmeter. It uses a mechanical measuring element to continuously divide the fluid into a single known volume portion, and measures the total volume of the fluid based on the number of times the measuring chamber is repeatedly filled and discharged. Positive displacement flowmeters can be classified into oval gear flowmeters, scraper flowmeters, dual rotor flowmeters, rotary piston flowmeters, reciprocating piston flowmeters, disc flowmeters, and liquid-sealed rotary drum flowmeters according to their measuring elements. , Wet gas meter and membrane gas meter, etc. Features: Advantages: (1) High measurement accuracy; (2) The installation pipeline conditions have no effect on the measurement accuracy; (3) It can be used for the measurement of high-viscosity liquids; (4) The range is wide; Clear and easy to operate. Disadvantages: (1) Complex structure and huge volume; (2) The type, diameter and working state of the medium to be measured are relatively limited; (3) It is not suitable for high and low temperature occasions; (4) Most instruments are only suitable for clean single-phase fluid; (5) Noise and vibration. ?? The pressure loss is large; 5. The orifice plate has an acute angle line in the inner hole to ensure the accuracy, so the sensor is sensitive to corrosion, wear, scaling, and dirt, and the long-term use accuracy is difficult to guarantee. It needs to be removed and checked once a year; The blue connection is prone to problems of running, running, dripping and leaking, which greatly increases the maintenance workload. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Huasheng Instrument--Positive Flow Meter'
