V-Cone flowmeter is a new differential pressure flow measuring device V-cone flowmeter is a new variety of Reynolds numbers can be accurately measured with high precision flow meter, a variety of media to meet the requirements of the application conditions of its operation principle of differential pressure principle with other types of the same, are sealed in the pipeline based on energy conservation theorem, cone flowmeter Due to the unique design of the structure, and therefore better performance. Cone flowmeter is hanging in the pipeline at the center of a conical orifice, tapered piece impede the flow of the medium, remodeling velocity curve, a low pressure area, the pipeline upstream of positive same verses immediately downstream of the cone between the negative pressure downstream of the flow restrictor member after a differential pressure, the positive pressure port for taking out negative pressure, the positive pressure port is located on the pipe upstream of the negative pressure outlet port at the end of the cone, and by measuring between the differential pressure, according to Bernoulli's equation to calculate the flow rate of the pipeline, the pipeline is located in the center of the cone, can be measured on the velocity curve to optimize the media, so the high accuracy of the instrument, the downstream straight pipe requirements low. Cone flowmeter can measure a variety of conditions (temperature and pressure) conditions in a gas phase, a mixed gas, liquid, multiphase fluid, the gas-liquid two-phase (moisture, liquid mass ratio ≤5%), powders, high Flow viscosity, high velocity, dirt, liquid containing solid particles in suspension in a solution of vibration, electromagnetic interference, and other media. Low temperature conditions of the fluid from the deep to the supercritical state. Operating temperature up to 850 ℃, the maximum pressure 42.0MPa. If using the special structure of the material, temperature and pressure can also be higher. Measurable highest Reynolds 5,000,000, the lowest Reynolds number 8000 or even lower. Full-scale differential pressure signal is less than 0.1 kPa from the lowest to the highest scores kPa. Conical flange pressure type flowmeter (VF), the use of solid cone closure body and the wall with the flange pressure, coupled with remote differential pressure transmitter, which can effectively prevent the clogging taps, suitable for medium containing solid particles of dust, dirt and liquids of high viscosity media. Works with the principle of differential pressure flow meter has been designed for the application of a hundred years of history, differential pressure type flow meter is based on the seal piping energy conversion principle, ie to stabilize the fluid pressure in the pipeline pipeline flow rate is inversely proportional to the square root of the medium: the speed increases the pressure drop, when the medium close to the cone, which pressure is P1, in the area of ??media through the throttle cone, the speed will be reduced to increase the pressure P2, as shown in Figure 1 , P 1 and P2 are diverted to the rear differential pressure transmitter connected to the meter via a conical taps, occurs when the flow rate changes, differential pressure flowmeter will taper between the two taps increases or out. When the differential pressure the flow rate is the same, if the throttling area, that is generated is large, β is equal to the cone area divided by the throttle cross-sectional area of ??the pipe diameter (which can be converted to the diameter ratio between the two). Is a new differential pressure flow measuring device, and a unique way of side walls gradually shrink throttle, throttle changed the traditional shortcomings of almost Therefore, differential pressure flowmeter revolutionary results, it can be widely used in petroleum , chemical, electric power, heat supply and other areas of the national economy, the scope of application of the V-Cone Flow Meter Product Selection Principle V cone flowmeter Model Description KH-LVD V cone flowmeter Code caliber (mm) 15 ~ 3000 DN15 ~ DN3000mm each component material Material Code cone pipe flange A SS304 20 # 20 # B SS304 15CrMo 15CrMo C SS304 SS304 20 # D SS304 SS304 SS304 E SS316L SS304 SS304 G SS316L SS316L SS316L # other materials codenamed medium liquid vapor 4 3 2 gas temperature medium codenamed compensation N form without pressure, temperature compensation Q with pressure, temperature compensated output code screwed connection form L (for small caliber) W flanged Code Pressure Level 0 0.25MPa 1 0.6 MPa 2 1.0 MPa 3 1.6 MPa 4 2.5 MPa 5 4.0 MPa 6 6.3 MPa
