One-piece Thermowells

To compliment our supply of temperature instrumentation (RTDs and thermocouples) Fluidic offer industrial grade thermowells for inline temperature measurement.  We can supply one-piece thermowells  in materials compliant to NACE MR0175 which have no welds that may be susceptible to premature pitting or corrosion.


The primary function of a thermowell is to allow efficient thermal transfer of the process media through to the temperature measurement instrument.  To reduce response time, wall thickness of the thermowell should be no more than is necessary to maintain suitable strength for application.  This should consider not only the forces acting on the thermowell by velocity and mass of the fluid, but give consideration to wake frequency.  With process data information, Fluidic are able to supply wake frequency calculations with any thermowell proposal, helping with initial design concept before manufacture.


Thermowells and thermowell assemblies from Fluidic…

  • Wake Frequency Calculations with bid (as required)
  • Bar Stock thermowells with full penetration weld
  • One-piece, forged thermowell options
  • 316SS as standard with Super duplex and hastelloy options
  • NACE MR0175 material options (Sour Gas Applications)
  • Tapered, stepped or parallel options
  • Full temperature transmitter and RTD assemblies


Via our partnership H&B Sensors, Fluidic are able to supply complete temperature instrumentation assemblies.  This would normally comprise of the thermowell, temperature sensing element and transmitter puck.  Our instrumentation engineers are product trained and are able to help with instrument selection within the full H&B Sensors supply scopes.  A lot of temperature instrumentation can be custom made for application.  Please call either office for more information (Glasgow 0141 641 5920,  Warrington 01925 572401).
