The float acts as an indicator for the flow direction and flow rate. – Display range up to ± 4 l/min – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling nipples – Quick-action mounting system Quick-Fix Order no. 3492037 2 Flow indicator with float Mechanical flow indicator according to the float principle for measuring the flow in l/min und gal/min (US). – Can be used whatever the position, spring return – Directly readable – Measuring range: 0.5 – 4.5 l/min or 0.1 – 1.2 gal/min – Maximum permissible pressure: 12 MPa (120 bar) – Low leakage oil, self-sealing couplings Order no. 4857121 3 Measuring container for hydraulic oil The transparent measuring container is designed with a calmed inlet, a normal inlet, and an inlet for unpressurized return. There is also a scale, an overflow protection and a drain that can be opened manually. The universal bracket (order no. 539736) is required for mounting to Learnline. Measuring range up to 2 liters. Order no. 541134 4 Flow sensor The sensor is coupled to the hydraulic motor (order no. 152858). A tachogenerator converts the hydraulic motor’s speed in rpm into a DC voltage. A speed of 0 to 1220 rpm of the hydraulic motor corresponds to a voltage of 0 to 10 V and a flow rate of 0 to 10 l/min. – Clockwise/counterclockwise rotation: output as analog value from 0 – 10 V – Operating voltage: 24 V DC – Measuring range 0 – 10 l/min – Analog output: 0 – 10 V – Electrical connection on 4 mm safety sockets Order no. 567191 3 4
