Volumetric flowmeters, also known as fixed displacement flowmeters, referred to as PD flowmeters, are the most accurate type of flowmeters. It uses a mechanical measuring element to continuously divide the fluid into a single known volume fraction, measuring the total volume of fluid according to the number of times that the measurement chamber fills and discharges the volume fraction of fluid one after another. Volumetric flowmeters are classified according to their measuring components and can be divided into oval gear flowmeters, scraper flowmeters, dual-rotor flowmeters, rotary piston flowmeters, reciprocating piston flowmeters, disk flowmeters, liquid-sealing tumbler flowmeters. Wet gas meter and film gas meter.
Features:
advantage:
(1) High measurement accuracy;
(2) Installation pipeline conditions have no effect on the measurement accuracy;
(3) can be used for the measurement of high viscosity liquids;
(4) Wide range;
(5) Direct-reading meters can be directly accumulated, total, clear, and easy to operate without external energy.
Disadvantages:
(1) The structure is complicated and bulky;
(2) The types of medium to be measured, the caliber, and the working status of the medium are more limited;
(3) Not suitable for high and low temperature applications;
(4) Most meters are only suitable for clean single-phase fluids;
(5) Generate noise and vibration.
5, the hole plate to ensure the accuracy of the inner hole acute angle, so the sensor is sensitive to corrosion, wear, scaling, dirt, long-term use of precision is difficult to guarantee, need to remove the strong inspection once a year;
6, using flange connection, easy to run, run, drip, leakage problems, greatly increasing the workload of maintenance.
