Wireless Guided Wave Radar, 3308A - Can I cut the probe for adjustment the large ?

We have a Wireless Guided Wave Radar, 3308A  (complete model: 3308ASX2D1I5S1V6AAR4SM00684WA3WK1M5Q4) with 684 cm probe length

My problem is the vertical dimension availble at tank is 607 cm

Can I cut the probe for adjustment the large ?

I need instruction about how must cut it (ROSEMOUNT procedure if available and/or tutorial videos) 

Thanks for your attention

  Hello Cristian,
  Yes, all probes, except for the PTFE covered probes, can be cut to fit in the field. Note that the shortest recommended probe length is 400mm though. Also make sure to update the transmitter configuration with the actual probe length, after the cut. Note that you will find an entire chapter in the reference manual about how to shorten the probes.
  Kind regards,
  Ingemar

  Hello friends:

  Plzz solve my problem I have a brand new 1" vertex flow meter 8800D 

  I install vertex in adible oil. The problm is that i am open control valve is 40% then flow is 4 T/h and veriation is too much and then I am valve open 45% or 50% then flow is 5 T/h or 6 T/h and no veriation, flow down, no hamring. Flow is very smooth and Good but then valve open is 40% then now situation too bad the flow down, hamring, veriation and not smooth.

  Help me this situation how am I solve this problem

  Hello Awaiz. I'm not sure how you ended up posting here under a Guided Wave Radar posting, so I'll encourage you to follow up with an email directly to our Vortex Flow Support Team (flow.support@emerson.com). Please do not reply again under this post. With that said, this is likely one of two issues: 1) The pipe isn't staying full at the lower flow rate (should be installed in vertical pipe flowing up, or in a low point in horizontal line, or with sufficient backpressure to maintain full liquid cross section at all flow rate), or 2) the digital filter settings are too low, allowing additional process noise into the flow signal at lower flow rates. Make sure you've optimized your filters for a liquid density (typically 640 kg/m3) which should clean up the liquid flow signal. If you have questions about how to do this, consult the 8800D manual, or contact our flow support group at the email above. Thanks.
