What type of thermometer installed on pipe

What type of thermometer installed on pipe? Instrument answer: pipeline is usually installed on the bimetallic thermometer, surface water meter, thermometer, so this a few kinds thermometer thermometer is also called pipes. Pipeline is ubiquitous in our normal life, the use of pipeline has great effect on social and economic development, so the pipeline thermometer for the installation of pipelines is very important. Bimetallic thermometer is a round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. High water meter can measure pressure PSI and KPA, and water temperature degrees Celsius and Fahrenheit. High water meter is designed for hot water heating system, hot water boiler, swimming pools and other equipment design, be able to give a fast and accurate temperature indicator. High water meter is a kind of field detection instrument suitable for measurement of low temperature and pressure, can be used to directly measure the temperature of the liquid, gas, and the pressure inside the container. Is now widely used in many different areas, users in the use of this instrument is very satisfied, became one of very important equipment in processing production. Surface thermometer is to rely on the principle of the double metal heat bilges cold shrink principle of sensors to work, by contact spring or magnet at the bottom of the thermometer to measure the metal surface and reading. This type of double metal surface thermometer can range from - 40 c to 500 c, the precision can be in for some using occasions for accuracy is not high, can yet be regarded as a money and cheap thermometer of beauty.
