This structural feature of the venturi makes it free from sharp edge abrasion and fouling problems similar to orifice plate throttling parts in the use process, and can effectively adjust (rectify) the flow velocity distribution gradient of the fluid in the tube before throttling and various possible non axisymmetric velocity distributions, so as to achieve high-precision and high stability flow measurement, which is widely used in various fields of national economy such as metallurgy, power, coal, chemical industry, etc.

Papua New Guinea V-cone flow sensor

V-cone flow sensor is a new differential pressure flowmeter, which can accurately measure flows of all kinds of conditions in a wide range of Reynolds number. Like other differential pressure flowmeters, it is based on Bernoulli equation of conservative energy of fluid flowing continuously in closed pipes. For ideal fluids, the velocity of medium is proportional to the square of differential pressure.

Papua New Guinea Elbow flowmeter

As a new measuring product which has a long history, elbow flowmeter has been recognized by the metrology field. It has been widely used in many industries, such as thermoelectricity, thermodynamics, metallurgy, petrochemical industry, food and public utilities. Its application and development prospects are very broad. The main advantages of elbow flowmeter are reliable principle, simple structure, energy saving, less maintenance, etc. The primary sensor of elbow flowmeter, i.e. the elbow sensor, has good applicability for all kinds of harsh situation such as high temperature, high pressure, humidity, dust, vibration. It can accurately measure the flow rate of pipes with a diameter of φ10-p3,000mm or even larger.

Papua New Guinea Weizhanba flowmeter

In flow measurement, due to the complexity of the measurement medium, there are many kinds of measurement methods, so there are various flow sensors or throttles based on different measurement principles. According to the measurement methods and structures, they can be divided into: differential pressure type, float type, volumetric type, turbine type, electromagnetic type, vortex type, ultrasonic type, thermal type and Coriolis type. According to the installation modes, they can be divided into insertion type, closed pipeline type and open channel type. Weizhanba flow sensor manufactured with advanced technology is a flow sensor designed according to differential pressure working principle and insertion installation method. Its bullet-shaped cross section which fully conforms to the aerodynamic principle, high strength seamless integral structure, low-pressure hole design with its own anti-blocking ability and other technologies are in the leading position in the world.
