Currently, we use a mass flow <br>controller, which in the case of an outage which would outlast the UPS <br>would close. The solution is to change this to a mass flow transducer on <br>the detector inlet, which would be supplied by a standard rotameter <br>installed in the gas shed. This set up would then supply gas in any <br>condition and still be adjustable without entering the Hall.<br></div><div><br></div><div>The rough estimate for the new equipment would be approximately $3200 <br>which would include one transducer, plus a spare, and a rotameter. <br>George is preparing an dollar figure quote and augmenting the drawings.<br></div><div><br></div><div>Once you receive the quote from us, please let us know how to proceed <br>with the procurement as soon as possible.<br></div><div><br></div><div>Thanks,<br></div><div><br></div><div>-- <br>Marc McMullen<br>Detector Support Group<br>757-269-7738<br></div><div><br></div><div>_______________________________________________<br>Dsg-htcc mailing list<br>Dsg-htcc@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-htcc<br></div><div><br></div></body></html>
