Applications
High precision capillary tube is used in many Instrumentation systems which include the use of:
1. HPLC tubing
2. UPLC tubing
3. Coriolis tubing
4. Remote seal pressure transmitter tubing
5. Sheath tubing
6. Hydraulic tubing
Some applications require long lengths of stainless steel coil tubing where joints (welds or fittings) are not acceptable over long runs. However, there are many critical capillary applications which require short lengths of tubing.
Other high precision devices which use this type of capillary tubing include:
1. Manometers
2. Flow Meters
3. Pressure meters & sensors
4. Differential pressure transducers
5. Pressure, level, flow and temperature transmitters
6. Bourdon-tube gauges
7. Coriolis flow meters
