Contact flow&level instrument advantages & disadvantages

 Contact flow&level instrument advantages & disadvantages 

Contact flow meter and level meter covers big market in the measurement instrument industry, we will discuss the contact flow & level instrument advantages and disadvantages.
I. Contact flow & level instrument measurement advantages:
1.1 The technology is mature and has high precision and reliability.
1.2 Enterprise instrumentation personnel have rich maintenance experience.
1.3 The instrument sensor is in full contact with the measured medium and can directly measure the inside of the medium.
1.4 The price is lower than the non-contact measurement method, and the selectivity is large.
1.5The enterprise has relatively mature metrological verification technology, equipment and experience.

II. Contact flow & level instrument measurement disadvantages:
2.1 Direct contact with the production medium has higher requirements on the material properties of the sensor contact surface (such as corrosion resistance, heat resistance, etc.).
2.2 The sensor may be deformed or damaged by direct force.
2.3 If the material is easy to crystallize and has high viscosity, it will adhere to the sensor and cause inaccurate measurement.
2.4 Maintenance is inconvenient, affecting continuous production, and there are potential safety hazards for maintenance personnel to contact the medium.
2.5 There are many openings in the equipment, which is prone to the phenomenon of "running, dripping and dripping".
2.6 Insulation, heat tracing, anti-corrosion, etc. must be carried out on the instrument and measurement drainage pipe, which affects the visual management of the production site.
2.7 The measurement range is affected by the instrument itself, and it may be used over the range, resulting in damage to the instrument.
