14 Set Z ero Flow On some applic a tions and in so me conditions it may be that altho ugh there is no flow the instrument m ay show a small offset due to sy stem n oise. T he offset can be cancelled out and w ill increase the accuracy of the instru ment.
15 Measurement µ µ µ µ s A point in the sig nal transm itted, where the f low m easurem ent is taken from . It is used to see if the sign al is being taken from th e burst at the correct time to get the strong est signal.
16 Warning Messages W1: CHECK SITE DATA This mes sage occurs w hen the application inf ormation has been entered in correctly an d the w rong sens ors have been attached to the w rong pipe s ize causing the sy stem timing to be in error. The site data needs to be ch ecked and the instru men t reprogram m ed.
17 Enter a lining th ickness first This mes sage appears w hen in VIEW/EDIT SITE DATA the user has tried to enter a pipe lining m aterial before entering a thick ness. APPLICATION INF ORMATION The PORTAFL OW 216 is a Transi t Time u ltrasoni c flow m eter.
18 TRANSDUCER POSITIONING As th e transducers f or the Portaflow 216 are clamped to the ou tside surf ace of the pipe, the m eter has no w ay of determining exactly w hat is h appening to the liquid.
19 An u neven surf ace that prevents the transducers f rom sitting f lat on the surface of th e pipe can cause Signal Lev el and Zero Off set problem s. The follow ing procedu re is offered as a guide to g ood practice with respect to positionin g and moun ting the tran sducers.
20 If the Portaflow 216 is to be us ed on lam inar flow applications it will be n ecessary to calculate the Rey nolds No f or each application. To calculate the Rey nolds No it is n ecessary to know the Kinem atic viscosity in Cen tistokes; th e flow velocity and the pipe insi de diameter.
