Hello everybody!
We have many GWR installed in bypass chambers. Could you clear next issue, from where level meter starts calculating distance, from the begining of the probe or from the flange bottom surface? I'm asking because in RRM it is shown that we should measure tank height from the flange surface but in fact according to echo curve this point is shifted.

In reply to Artyom Krot:
We use the length from the nameshield in our configurations. But, there was one possibility to measure the total probe length of HTHP type with measuring tape. The result was, if we measured from flange it doesnt equal to the length on nameshield. Actually we have difference about 15 cm. And if we measured probe from the end to the begining where it is close to transmiter head we get the length written on the nameshield. In this case do we also have to use the length from flange and not from the begining, which is given on nameshield?
Best regards, Artem

Artem,
The probe length on the model code should reflect its physical lenght between reference pont and probe end according to the attached picure (copied from the 5300 product data sheet). Note that you need to key in the actual probe length into the database in order to get the most out of the functionality. If the probe was longer than ordered/stated by model code, you can shorten it - you will find detailed instruction on how to proceed in the 5300 reference manual. BR/Ingemar
One reason why the physical probe length doesn't match the model code on the label might be that the probe doesn't belong to this transmitter head; if you for instance make all the mechanical installations (installing the probes on the tank flanges) with the probe assembly separated from the transmitter head - and make the electrical installation later (then with the transmitter head in place) - it is common that the transmitter head ends up on a probe that was delievered together with another transmitter head. This is not really a problem - as all probes matches all 5300 transmitter heads - but you then need to set the database up accordingly.
