Hot Oil Flow Meter Overview
A differential pressure flowmeter refers to an instrument that measures the flow rate based on the differential pressure generated by the flow detector installed in the pipeline, known fluid conditions, and the geometric dimensions of the detector and the pipeline. The hot oil flow meter belongs to differential pressure flowmeter,at the same, it is also industrial flow meter. The hot oil flow meter consists of a primary device (throttling device) and a secondary instrument (differential pressure conversion and flow display instrument). In particular, the newly emerging intelligent differential pressure transmitter is integrated with the throttling device, which not only brings great convenience and benefits to the installation, users do not need to lay installation pipelines, but also can realize automatic compensation of temperature and pressure, failure Functions such as diagnosis, very wide range, on-site range adjustment, and communication with the upper computer further expand the scope of application of the throttling device.
In the production process of petroleum, chemical industry, metallurgy, electric power, light industry, light textile, scientific research, military industry and other industries, various types of differential pressure flowmeters are still widely used for flow measurement, control and regulation. Since the differential pressure flowmeter has the advantages of simple structure, firmness, reliable operation, stable performance, moderate accuracy, and low price, its usage still occupies an absolute advantage.
Hot Oil Flow Meter Structure
The standard orifice plate of the hot oil flow meter can be divided into three types according to the pressure taking method: corner joint pressure taking (including Carrier ring pressure tapping standard orifice structure and separate drilling pressure tapping standard orifice structure), flange pressure tapping and radial distance pressure tapping (D-D/2). Among them, radial distance pressure tapping is rarely used, please consult us for structural details.

Hot Oil Flow Meter Working Principle
When the fluid filled with the pipe flows through the throttling piece in the pipe, as shown in the figure, the flow velocity will form a local contraction at the throttling piece, so the flow velocity will increase and the static pressure will decrease, so pressure will be generated before and after the throttling piece Difference. The greater the fluid flow rate, the greater the pressure difference generated, so that the flow rate can be measured in terms of the pressure difference. This measurement method is based on the flow continuity equation (law of conservation of mass) and the Bernoulli equation (law of conservation of energy). The size of the pressure difference is not only related to the flow rate but also to many other factors. For example, when the form of the throttling device or the physical properties (density, viscosity) of the fluid in the pipeline are different, the pressure difference generated under the same flow rate is also different.
