Orifice plate flow meter

The standard throttling device can ensure its measurement accuracy without actual flow calibration. (Unique among all flow meters);
The measured medium is very wide and can be used for flow measurement of almost all gases, steam and liquids;
The applicable diameter ratio β is 0.22~0.75, Reynolds number ReD≥5000, pipe diameter DN50~1000mm, and extrapolation to 5000mm is allowed. β=d/D, d—orifice opening diameter; D—actual inner diameter of the pipe
The operating pressure can be as high as 32MPa, and can also be used for negative pressure;
Medium temperature range: -30℃～+650℃;
The product uses an intelligent differential pressure transmitter, which can set the differential pressure value (within the specified range) on-site through buttons or communication methods according to the changes in the flow of the measured object, thereby changing the flow range and greatly widening the system flow range;

Product Overview：

Application: The throttling differential pressure flowmeter consists of three parts: throttling device, differential pressure transmitter and flow totalizer. The throttling device is the primary element directly installed on the pipeline, and the differential pressure transmitter and totalizer are secondary elements. It is mainly used for the flow of various gases (pure or dusty), steam (saturated or superheated) and liquids (conductive or non-conductive; highly corrosive; viscous or containing tiny particles) flowing through the pipeline. It can directly measure volume flow or mass flow.

Conditions of use:

1) In the measuring section, the fluid must fill the circular tube and flow continuously through the throttling device;

2) The fluid must be physically and thermodynamically uniform single-phase fluid;

3) The fluid measured by the throttling device must be a stable flow, or can be regarded as a stable slowly changing fluid. It is not suitable for pulsating flow and critical flow measurement;

Solicitud:

Tap water and sewage treatment: Orifice flowmeters can be used to measure the flow in tap water and sewage treatment, which helps to achieve the rational allocation and effective use of water resources.

Chemical and petrochemical: Orifice flowmeters are widely used in the chemical and petrochemical industries to measure the flow of various industrial fluid media, such as various chemicals, raw materials, etc.

Cooling water system: Orifice flowmeter can be used to measure the flow of industrial cooling water, which helps to monitor the operating status of the cooling water system and ensure the normal operation of the equipment.
