throttling device, also known as differential pressure flowmeter, Orifice flowmeter contains (integrated orifice flow meter, standard orifice, annular orifice flow meter, integrated annular orifice flow meter)

Nozzle flow meter (integrated nozzle flow meter)can be divided according to function name gas flow meter, flue gas meter, steam flow meter, gas flow meter, compressed air flow meter, liquid flow meter.

 

Throttling coffret - nozzle flowmeter has many advantages, but generally feel pressure pipeline installation on site work is large, also easy to leak, congestion and other issues. Differential pressure transducer made by leaps and bounds in recent years of development, not only the small size, and stable performance, easy to adjust, in use process basically don't need to adjust the zero point. These advantages contribute to a body orifice flowmeter (including orifice plate, the annular orifice, nozzle, etc.) in the development and application. Nozzle flow meter is to measure flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Standard nozzle throttling device with differential pressure transmitter, can measure the rate of flow of liquid, steam, gas, nozzle flowmeter has a long history background, all kinds of test data is complete. Simple structure, no moving parts, stable and reliable long-term use, rich experience in design and manufacture and application. Doesn't need a high degree of standardization, solid flow calibration. Standard orifice has reliable experimental data and improve the international and national standards. In foreign countries and has its inherent in the huge domestic market, users are familiar with, data; Follow the international standard calculation and processing, use agile and convenient; According to relevant data of estimate of flow meter between 60% and 70% of the total consumption. It is widely used in petroleum, chemical, metallurgical, power, light industry and other departments.

 

Features:

 

Nozzle flowmeter smaller pressure loss;

To save energy;

More strong and durable;

Suitable for high temperature and high pressure fluid;

Widely used in electric power, chemical and other industries of steam flow measurement;

Nozzle flowmeter include standard nozzle (ISA1932 nozzle) and two long neck nozzle. The design and manufacture are in accordance with international standard ISO5167 or the provisions of the national standard GB/T2624.

 

Standard nozzle plane perpendicular to the axis of the entrance by part A, circular arc form surface contraction section B and C of entrance, the edge of cylindrical throat E and to prevent damage to the protective tank F, pressure from its ways upstream pressure mouth Angle of using access, downstream take pressure can be set up by the pressure of Angle joint, also can be set up in the far downstream.

The total length of the nozzle

When 0.30 beta 2/3 or less or less, the nozzle length = 0.6041 d

When two-thirds beta 0.80 or less or less, the nozzle length = {0.4041 + (0.75 / beta 0.25 beta 2-0.5225) 0.5} d

SKLGB type series nozzle flowmeter throttle device upstream face by perpendicular to the axis plane and profile for the two arcs of a circular, cylindrical throat and groove for the identified contraction of the nozzle. SKLGB type series nozzle flowmeter throttle device way of selecting pressure Angle only pressure a pick up.

Length to diameter nozzle upstream face by perpendicular to the axis plane and profile for the quarter ellipse contraction, cylindrical throat and possible grooves or Angle of the nozzle. Length to diameter of nozzle take pressure way - D / 2 D only take one pressure.
