Hi,
Recently i am doing with a datasheet of a Radar type level transmitter.But i am findings difficulty with the terminology (Measurement-Section) attached in the image.How could i define HmHiTL(SL-76) as there is no indication about it in vessel specification. or what should be the Maximum measuring height Hm(SL-74) where my HTL is 4500 and HLoTL is 750.Is there any thumb rules for detailing these or any calculation procedure.As before going to the vendors i want to be clear about this terms.Expecting kind suggestion from experts.
TIA.
