Product Overview
The SKLGV V-Cone Flowmeter is a novel differential pressure flow measurement device using a tapered cone (torpedo) coaxially installed inside the measuring pipe. Based on the Venturi principle, it combines the advantages of classical Venturi tubes, annular orifice plates, and wear-resistant orifice plates into a single integrated device.

Summary 2:
Features:
Short straight pipe upstream and downstream demand: straight pipe upstream of the shortest length is 3 d, (3 d) on the downstream side of the valve installation requirements, downstream straight pipe length for 3 d or less.
Accuracy: + / - 0.5%; Repeatability is 0.1%; A routine than 15:1.
The pressure loss of the resistance to dirt, small.
With the adjusting of the flow and the fluid mixing action.
Convenient installation, is the technical renovation of the ideal flowmeter;
Free maintenance, the workload is very small.
Short straight pipe before and after the request, generally only 0 to 3 d, upstream downstream only 0 to 1 d.
Loss of pressure is small, only 1/2 - one-third of orifice plate. Close to the venturi tube
V cone trailing edge to produce small vortex, the differential output stability, small fluctuations.
Without sundry stagnation, by cone thoroughly purge type design.
Throttling area of long-term stability, signal stability.
Summary 3:
Basic principles:
V cone flowmeter is a differentia pressure meter, its principle is based on the energy transformation in a closed pipeline Bernoulli's law. Using fluid continuity equation and Bernoulli's equation, the measured flow rate and output can be deduced the differential value of mathematical relationship. Is the law of conservation of mass continuity equation applied a mathematical expression of fluid movement. The type V cone flowmeter is a differentia pressure type flow meter, its is based on the law of conservation of energy in a closed pipe - Bernoulli equation and flow continuity equation, under the condition of the steady flow, pipe flow velocity and differential pressure in the direct ratio.
Measuring stability, flow coefficient remain unchanged for a long time.
High accuracy, good repeatability, and can realize flow of accurate measurement.
Range than wide, without secondary instrument software correction can reach 10:1.
Pieces of straight pipe installation requirement is low, small pressure loss.
The medium to be measured in pieces adaptability is strong, can measure the clean fluid, fluid containing solid grains, low pressure fluid, high humidity and various gas smudges fluid.
Flow components with self-cleaning function, resistant to wear and tear.
