Product Description<\/strong>
\n1. Working principle
\nThis type flowmeters is a differential pressure flowmeters, it get differential pressure to reflect flow rate through throttle. Throttling set is a cone a hanging in the pipeline central. High pressure the static pressure upstream PH (positive pressure) gets from the wall before the cone, low pressure(the pressure downstream) PL (negative pressure) gets from cone central, square root of the differential pressure DP is proportional to the flow.
\n2.General features:<\/p>\n(1)High measuring accuracy +\/-0.5%, trading version +\/-0.3%, good repeatability +\/-0.1%;
\n(2)Wide measure range (normally 10:1), low pressure loss, similar to Venturi tube type (is only 1\/10 or orifice plate type).
\n(3)Resistant to dirt, and little blockage.
\n(4)Good stability for long term;
\n(5)Can measure high temperature high pressure medium;
\n(6)Can measure complex medium flow (like multi-phase medium)<\/p>\n
