Notice for Contract Executors:Key Points for Installation and Maintenance of Differential Pressure Transmitters
Added to Favorites:125

I、Core Specifications for Differential Pressure Transmitter Installation

  According to the ISO 2186 standard,the installation location of a differential pressure transmitter should prioritize the medium characteristics and process requirements。For corrosive medium measurement,it is recommended to use Hastelloy diaphragms in professional equipment such as the China-Made Level Transmitter KL-DBS20 LCD Display Explosion-Proof Level Sensor,whose corrosion resistance is more than 3 times higher than that of 316L stainless steel。

1.1 Precautions for Mechanical Installation

  The mounting bracket must meet the strength requirements of ASTM A36 steel,and vibration damping pads must be added in vibrating environments。Typical error cases show that failure to use dedicated sealing gaskets can result in 40% measurement error。

Installation StageTechnical ParametersEN Standard
Pressure Tap LocationDistance from elbow≥10 times pipe diameterEN 60534-8-1
Impulse Pipe Inclination≥1:12 slopeEN 13480-3

II、Maintenance Cycle and Key Indicators

  Zero-point calibration is recommended every 6 months,and explosion-proof equipment must strictly follow the IEC 60079-19 maintenance procedures。A case from a petrochemical enterprise shows that regular maintenance can extend the service life of an electromagnetic flowmeter to 15 years。

2.1 Common Troubleshooting

  • Output Fluctuation:Check whether liquid has accumulated in the impulse line,and the probe of an ultrasonic flowmeter needs to be cleaned
  • Zero-Point Drift:Perform static pressure calibration again
  • Communication Interruption:Verify the HART protocol configuration parameters

III、Special Notes on Contract Execution

  During the project acceptance stage,it is necessary to focus on checking whether the turndown ratio of the differential pressure transmitter meets the 1:100 standard agreed in the contract。Technical evaluation personnel should require the supplier to provide third-party test reports,especially for application scenarios involving SIL3 safety rating。
