An overview of orifice bimetallic thermometer

Orifice bimetallic thermometer, throttling device is also called differential pressure type double metal thermometer, is composed of a detection ( The throttle) And the second device ( Differential pressure transmitter and flow display) Widely used in the gas. Steam and liquid flow measurement. Has a simple structure, convenient maintenance, stable performance, reliable use, etc. 8 q3 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

orifice bimetallic thermometer works full of throttling device in the piping of the fluid flowing through a pipe, near the throttling a local contraction, velocity increases, the upstream or downstream in the static pressure difference on both sides of the. Under the condition of known related parameters, according to the principle of flow continuity and Bernoulli's equation can be deduced the relationship between the pressure and flow rate and flow rate are obtained. The basic formula is as follows: 8 q3 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

1. Orifice of the bimetallic thermometer structure performance is good, it's the throttling device structure is simple, stable and reliable performance, service life is long, often used in industry. Orifice bimetallic thermometer at the time of design, completely is designed in accordance with international standards, the bimetallic thermometer can be rest assured to buy. 8 q3 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

2. Using orifice bimetallic thermometer can increase the flow velocity, reduce the static pressure, produce pressure difference before and after in the throttle at the same time, control the flow of the medium. Therefore, using orifice bimetallic thermometer to measure the flow of fluid size is very helpful. 8 q3 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

3. Orifice bimetallic thermometer can measure all kinds of fluid flow in pipes, such as gas, steam, liquid, and so on, these fluid used in petroleum, light industry, metallurgy industry, etc is very broad, therefore, the emergence of orifice double metal thermometer, promote the development of the industry. 8 q3 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
