Notes on installation of smart differential pressure transmitter? Next, I will explain it for everyone:
The intelligent differential pressure transmitter should be installed perpendicular to the degree; the measurement point of the intelligent differential pressure transmitter is at the same level as the installation, otherwise the correction of the additional height error is considered. The distance between the installation of the intelligent differential pressure transmitter and the measurement point should be Keep it as short as possible, so as to ensure the tightness of the seal slowly, and no disclosure should occur, especially for flammable and explosive gas media and toxic and harmful media.
In the following cases, additional devices should be added to the application of the intelligent differential pressure transmitter, but no additional error should be generated, otherwise correction should be considered.
(1) In order to ensure that the instrument is not affected by the measured medium or the viscosity is too large, an isolation device should be installed;
(2) In order to ensure that the instrument is not affected by the sudden change of the measured medium or the pulsating pressure, the installation of a buffer, especially when the pressure increases sharply and the pressure drops sharply, it is easy to use the instrument to destroy the scrap, and even the spring tube cracks, resulting in disclosure;
(3) In order to ensure that the instrument is not affected by vibration, pressure gauges should be equipped with shock absorption devices and fixtures;
(4) In order to ensure that the instrument is not affected by the high temperature of the tested medium, a pipe bend device filled with liquid should be installed;
(5) It is strictly forbidden to use other special instruments, and it is strictly forbidden to measure on unreliable devices. It is strictly forbidden to use general pressure measurement as special media;
(6) For newly purchased pressure measuring instruments, before installation and application, measurement verification must be carried out to prevent the accuracy of vibration or other factors from being damaged during transportation.
