flow meter for liquid media flow-captor 4311.30 The flow-captor Type 4311.30 is a non-reactive flow meter, ideal for all measurement and control tasks in automation processes or other industrial applications. The 4311.30 is an inline model specially designed for installation in smaller pipe diameters. The sensor works according to the calorimetric measuring principle. The detection takes place in the inline tube, whereby the sensor measures the "heat flow" depending on the flow velocity of the medium and converts it into a linearized, flow-proportional, electrical signal. • • • • • • • for small pipe sizes from ID6 up to ID25 analogue current output 4 – 20 mA ideal also for lower flow velocities robust industrial design (fully encapsulated) electronic no mechanically moved parts ISO 9001:2015 Technical data Type Medium Sensor data Measuring range Medium temperature Ambient temperature Response time Linearity deviation Repeatability Temperature-drift Mechanical data Protection class Operation pressure Material housing Material of sensor tube Torsion Tube to housing Sensor tube (mm) diameter x wall thickness Housing dimensions (mm) 4311.30 water-based (oil-based on request) 0 - 20 cm/s to 0 - 100 cm/s, cont. adjustable * -10 °C to +80 °C -10 °C to +60 °C 2 sec. - 10 sec. according to measuring conditions < 5 % (best fitting slope) <2% < 0.3 % K IP65 max. 30 bar Macrolon® stainless steel AISI 316Ti (other material on request) max. 10 Nm at medium and ambient temperature < 40 °C at higher temperatures no torsion allowed 8 x1 12 x 1 / 18 x 1,5 22 x 1,5 / 28 x 1,5 65 x 98 x 37 80 x 120 x 55 Electrical connection Electrical data Operating voltage Current consumption Output current Resistive load LED indication max. 100 mA 4 - 20 mA 0 - 600 Ω green LED: operation within the range: ON, operation beyond the range: OFF data relate to water www.captor.de [email protected] Tel.: +49 (0)4128 - 591· Fax: - 593 DE-25377 Kollmar Sensors GmbH Strohdeich 32 [email protected] Tel.: +44 (1704) - 551684 · Fax: - 551297 Merseyside PR8 4DU, UK 66 Eastbourne Road, Southport Sensors Ltd.
