Flow meter for liquid media flow-captor 4311.30M/xx The flow-captor type 4311.30M/xx is a non-reactive flow meter, ideal for all measurement and control tasks in automation processes or other industrial applications. The 4311.30M/xx 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. robust stainless steel construction (special potting) for smaller pipes from OD8 up to OD28 analogue current output 4 – 20 mA separate potentiometers for zero point and measuring range fully electronic functionality without mechanically moving parts LED display for output status ISO 9001:2015 Technical data Type Medium Sensor data *1 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 Torque of tube against housing Housing and tube dimensions Electrical connection Electrical data Operating voltage Current consumption Output current Resistive load LED indication *1) 4311.30M/xx water-based (other media on request) 0 - 20 cm/s to 0 - 100 cm/s, continuously adjustable -10 °C to +80 °C -10 °C to +60 °C 2 - 10 sec. according to measuring conditions < 5 % (best fitting slope) <2% < 0.3 % per Kelvin IP67 max. 30 bar stainless steel AISI 316 stainless steel AISI 316 (other material on request) ≤ 10 Nm see second page 2 m oilflex cable 24 VDC ±10 % max. 100 mA 4 - 20 mA 0 - 600 Ohm A green LED indicates operation within (LED on) and outside (LED off) of the set measuring range. www.captor.de Sensors GmbH Strohdeich 32 DE-25377 Kollmar Tel.: +49 (0)4128 - 591· Fax: - 593 [email protected] Sensors Ltd. 66 Eastbourne Road, Southport Merseyside PR8 4DU, UK Tel.: +44 (1704) - 551684 · Fax: - 551297 [email protected] Sensors LLC. 4462 Bretton Court, Building 1, Suite 7 Acworth, Georgia 30101, USA Tel.: +1 (770) 592 - 6630 · Fax: - 592 6640 [email protected] Technical data subject to al
