V-Cone is a new differential pressure flow metering device V-cone flowmeter is a new variety of the Reynolds number can be accurately measured with high precision flow meter, a variety of media to meet the application requirements of the conditions of its operation principles with other types of differential pressure principle is 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, cone pieces impede the flow of the medium, remodeling velocity curve, a low pressure area, the pipeline upstream positive with verses immediately downstream of the cone between the negative pressure downstream of the flow restrictor member after a differential pressure, positive, negative pressure taken out by the pressure taps, the positive pressure port is located upstream of the pipe, negative pressure outlet port at the end cone, by measuring between differential pressure, according to Bernoulli's equation to calculate the flow in the pipeline, the pipeline is located in the center of the cone, can be measured on the velocity curve media optimization, so high accuracy of the instrument, downstream straight pipe requirements low. Cone flowmeter can measure a variety of conditions (temperature and pressure) conditions of the gas phase, a mixed gas, liquid, multiphase fluid, the gas-liquid two-phase (moisture, liquid mass ratio ≤5%), powder, high Flow viscosity, high velocity, dirt, liquid containing solid particles in suspension in a solution of the vibration, electromagnetic interference and other media. The 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 special materials of construction, temperature and pressure can also be higher. Measurable highest Reynolds 5 million, 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 flowmeter (VF), the use of a solid cone closure body and the wall with the flange pressure, coupled with remote differential pressure transmitter, which can effectively prevent clogging of the taps, suitable for medium containing solid particles of dust, dirt and high-viscosity liquid medium. Works with the principle of differential pressure flow meter has been designed for the application of a hundred years of history, the differential pressure type flow meter is based on the seal piping energy conversion principle, that is to stabilize the fluid pressure in the pipeline pipeline inversely proportional to the square root of the medium flow rate: speed increases the pressure drop, when the medium close to the cone, which pressure is P1, the medium through throttle cone region, the speed will increase the pressure will be reduced to P2, shown in Figure 1 , P 1 and P2 are introduced onto the differential pressure transmitter followed by cone flowmeter taps, occurs when the flow rate changes, differential pressure flow meter 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 throttling pipe diameter sectional area (can be converted to a ratio between the diameter). Is a new differential pressure flow measurement devices, and a unique way of side walls gradually shrink throttle, throttle almost changed the traditional shortcomings So, differential pressure flow meter is a revolutionary results, it can be widely used in petroleum , chemicals, electricity, heat supply and other areas of the national economy, the V-Cone V-Cone Flow Meter Applications Product Selection Model Description principle KH-LVD V-Cone 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 Material Code medium liquid gas 3 4 medium heat steam compensation code N forms without pressure, temperature compensation Q with pressure, temperature compensated output code threaded connection form L (for small caliber) W Flange 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
