Intek Inc. is a leader in precision
thermal flow instruments offering unique
non-contact flow measurement solutions
for many gases and liquids
Intek was founded in 1976, with the goal of integrating advanced technologies
to solve complex flow measurement problems.  In early 1978, a major oil
company approached Intek with a flow problem.  The solution led to the
development of Rheotherm flow instruments: non-contact flow meters and
flow switches. The Company has built a reputation for highly accurate and
reliable flow measurement systems, capable of operating at low flow rates and
compatible with most industrial chemicals and gases.  Intek’s instruments
and services help customers in a wide range of industries, including Power
Generation, Nuclear, Chemical/Petrochemical, Pulp & Paper, Semiconductor,
Consumer Products/Packaging, and Water/Wastewater. Intek has supplied
many custom flow solutions for customers with unique flow challenges.

Intek's quality assurance program is certified to ISO 9001:2000  and is active in
supplying flow meters for the nuclear industry measuring fluids that expose
sensors to over 100 Mrad (lifetime).  In addition, the company has
manufactured equipment for the space program to the rigorous requirements
for NASA manned spacecraft.

Power Generation  
Measurement of condenser air in-leakage and other parameters
provides critical information to aid in operating a steam surface
condenser at peak efficiency.
Chemical / Petrochemical                
Chemical compatibility and non-contact sensor designs make Intek
flow meters and flow switches ideal for most chemical applications,
including aggressive environments.
Water / Wastewater Treatment             
From the low flow measurement of chemical additives, to the
demanding conditions of digester gas service, Rheotherm flow meters
and flow switches provide useful solutions to the water/wastewater
industry.
Biotech / Pharmaceutical               
Intek's TU and TUL flow sensors have an unrestricted non-contact tube
design that is ideal for chemical or steam sterilization.
Pulp & Paper                
Intek flow meters and flow switches are ideal for measuring the low
flow of anything from antifoamers to hardeners and dyes.
Nuclear          
Since the early 1980’s, Intek flow meters with radiation hardened
sensors have been used in services such as UF6, fuel reprocessing,
and nuclear power plant vent gas.
Food and Beverage Processing            
The TU and TUL flow sensor design, with 316 SS wetted surface and
no internal seals or other perturbations, can be easily cleaned and
sterilized.
Semiconductor                     
Sensor wetted material options include 316L SS UHP, Hastelloy C-276
and quartz.  Intek can even use your tubing, so the sensor material will
be from the same heat number as the rest of the system!
