The Krohne H250/RR/M40 is a variable area flow meter designed for vertical flow direction from bottom to top. It features a 300 mm installation length and utilizes a measuring cone type K 55.3 with a variator DIV 55, operating with a pressure drop of 65 mbar. The unit is constructed entirely with stainless steel 316L (1.4404/1.4435) for the measuring cone, connections, and float. Equipped with an NS 51/ 2" SMS screw connection and SMS 1146 threaded connector, it supports a measuring range of 2500 to 25000 l/h for water at 20 °C, 1 kg/L density, and 1 mPa.s viscosity. The device is housed in an M40 light alloy enclosure with an IP 66/68 rating, featuring a two-layer powder coating based on epoxy and polyester, an eddy current brake, and an M20x1.5 cable gland thread. It complies with DGRL parameter PED/G1/I/H for gases and liquids, handling a maximum permissible pressure PS of 6 bar, a maximum medium temperature TS of 120°C (248°F), and a test pressure PT of 10 bar.
