Oval gear flowmeter and volumetric flowmeter error analysis: volumetric flowmeter in flow meter is of high precision zui flow measuring instrument, its basic principle is to use mechanical measuring element to divide fluid continuously into a single known body. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the oval gear flowmeter scale and displacement meter scale error analysis for details. Oval gear flowmeter and volumetric flowmeter error analysis: volumetric flowmeter in flow meter is of high precision zui flow measuring instrument, its basic principle is to use mechanical measuring element to divide fluid continuously into the volume of a single known part, according to the measuring chamber again and again the number of full of emissions and the volume of fluid to measure the total fluid volume. Volumetric flowmeter of the flow range and types of measured medium ( Mainly depends on the fluid viscosity) And use the features ( Work continuous or intermittent) , measurement accuracy and other factors. In the field of industrial flow measurement, displacement meter and differential pressure flowmeter, flow meter and classified as three types of usage zui flowmeter, often used in expensive medium ( Oil, natural gas, etc. ) The amount of measurement. Volumetric flowmeter has the oval gear flowmeter, double rotor flowmeter, waist wheel flowmeter, scraper flowmeter, piston flow meter, such as type, the same displacement meter, for medium types, used for high viscosity fluid, the flow range is larger, Mainly the lower flow rate can be extended to a lower value) ； For using characteristic, is used for intermittent, its flow range is larger, Mainly is the limit flow can be bigger than continuous work) ； For measurement accuracy for low measuring accuracy, the flow range is larger, and for high accuracy measurement, the flow range is smaller. Also can see clearly from the flow characteristic curve. In order to maintain the performance of the instrument and longer service life, zui when using large flow zui persons to be good in instrument zui large flow rate of 70% 80%. As a result of the general volumetric flowmeter bulky, in the big flow will produce large noise, suitable for small and medium flow measurement commonly so. Combined with the performance of the volumetric flowmeter to measure mass flow, can be combined with 45 degrees waist wheel structure of the flow meter; In need of low noise work situations, can choose double rotor flowmeter. Oval gear flowmeter volumetric flowmeter is one of the high measurement accuracy zui flowmeter. Manufacturer on product samples given measurement accuracy refers to the basic reference conditions for error in the laboratory, in actual use, due to the site conditions, will inevitably bring additional error, the actual error should be basic and additional error synthesis. So when the instrument selection based on possible problems in the field measures should be taken. Site conditions on the influence on measurement accuracy of the influence of viscosity measured medium and temperature. The influence of fluid viscosity on the flow meter error characteristic is one of the factors for greater influence on the error of the flow, when the actual use of fluid viscosity and the laboratory test of fluid viscosity have bigger difference, should undertake the corresponding viscosity correction. If in addition to the fluid viscosity and other parameters have no obvious change, can be used for viscosity correction. About the above error characteristics of flow meter, compared with other types of flowmeter what are obvious different, users in the installation and use of elliptical gear flowmeter such displacement meter process need to pay attention to the following: (1) to determine displacement of volumetric flowmeter displacement is an important factor to ensure accuracy of displacement meter. Therefore testing on the size of the displacement components and physical properties are influence factors. 一个。 The temperature. As temperatures rise, fixed displacement components material body expansion make volume increases. Aluminum material flow meter, for example, the influence of the temperature is bigger than other material, the influence of flow meter. Typically, every increase 1 ℃ o F temperature, error increased 0. 02%. b。 Wear and tear. With the increase of using time, wear rate increase. But this usually wear more slowly and were predictable. c。 Viscosity. The viscosity of the liquid will form a thin film on the surface of in test element, with the increase of membrane thickness, fixed displacement will decrease until no longer increases (film thickness Due to the friction parts) 。 d。 Coating and precipitation. And viscosity caused by the principle of detecting element surface film, coating and a decrease in precipitation and the fixed displacement in the detecting element. For working condition of temperature close to the melting point temperature of some crude oil containing paraffin oil, its thickness changes will be very big. (2) the clearance leakage caused by displacement meter, the moving parts and the gap between the stationary parts, this is called the capillary sealing. Different fluid differential pressure resulting in the loss of fluid from the fixed displacement detecting element is an important factor caused the error. 一个。 The flow rate. Increase with the increase of fluid differential pressure, flow rate, therefore, drift also will increase, as shown in figure 2 1 79 curve. In addition, with the increase of pressure differential, parts of internal friction and increase torque drive components.
