High temperature and high pressure online viscometerWidely used in industries such as petroleum extraction, refining, chemical engineering, silicone oil, resin, food, chemical fiber, ink, paint, optical fiber, latex, solvents, plastics, glass, aviation kerosene, and various adhesives. Working principle: Using the principles of vibration (amplitude attenuation method) or rotation (rotor resistance method), viscosity is calculated by measuring the damping change of the vibrating rod in the fluid. For example, the electromagnetic oscillation waveform attenuation method achieves high-precision measurement by compensating for the proportional relationship between power and viscosity.
Matching of medium characteristics with sensor material:
High temperature and high pressure online viscometers require the selection of sensor materials based on the characteristics of the medium
Corrosive media: Hastelloy, titanium or zirconium materials are preferred.
High temperature and high pressure environment: 316 stainless steel (standard) or 2507 duplex stainless steel, with a temperature resistance of 350 ℃ and a pressure resistance of 25MPa.
Viscous liquid: To avoid adhesion, choose a material with a smooth surface (such as PTFE coating).
Installation method selection:
Flange installation: suitable for pipeline fixation, ensuring confidentiality, DN50 flange is a common specification.
Thread installation: G1.5-inch threads are suitable for small-diameter pipelines, and attention should be paid to thread sealing.
Immersion installation: The insertion depth needs to be controlled to avoid fluid impact on the sensor.
Split design (sensor and transmitter separated) is suitable for:
Complex working conditions: such as high temperature areas (sensor temperature resistance of 350 ℃) or vibration environments.
Convenient maintenance: The 10 meter four core shielded wire is easy to debug, and the IP66 protection level ensures safety.
