Nuclear

Rheotherm flow meters and flow switches are an ideal choice for many applications in the nuclear arena.  Intek combines tested sensor designs and years of experience with installations in radioactive locations.

Containment Air

An electric utility has used Rheotherm flow meters since 1983 to monitor the flow of air that is cycled through a post accident containment area of their nuclear plant.  A TU¼ transducer is used to measure a flow range of 0.3-3 SCFM.  The air is normally not contaminated, but could be highly radioactive in the event of an accident. 

Rheotherm advantage: radiation hardening, low maintenance, long-term reliability 

Vent Gas

Rheotherm flow meters have been in use for many years in the off gas line from a BWR.  Insertion probe sensors are threaded into 3” pipes.  Reliability cannot be compromised in this critical service, as the sensors are located in radioactive areas.  Replacement is time-consuming and expensive. 

Rheotherm advantage: radiation hardening, easy installation, standard volume output without external signal corrections

UF₆ Gas Flow

Intek has a long history of supplying flow meters for measuring the mass flow of UF₆ gas in nuclear fuel production. Customer feedback has been that Rheotherm meters work in this service when other meters do not. The first criterion for a meter is the sensor must withstand the radioactive environment. In addition the nonintrusive sensor design allows the lowest possible pressure drop for this low pressure gas service. Another factor is the longevity of our flow meters; with no mechanical parts and unstressed components, they can remain in service for decades.
