2 Description The OBOD Gear Wheel Flowmeter series DZR have been designed for a flow measurement for viscous liquids. The measuring unit consists of a pair of gear wheels which is moved by the flow according to the principle of gear wheel motor. The bearings are according to the material combination either ball bearings or gliding bearings. The movement of the gears is sampled without contact by means of two sensors located in the cover. Between sensor compartment and measuring chamber is located a pressureresistant, non-magnetic separator plate. The different versions vary through housing materials, bearing assembly, through the medium being used and the accuracy. The mounting position and flow direction is arbitrary.

13 Gear wheel flowmeter for viscous liquids odel DZR ATEX version Operation in ATEX area O O All volume counters are available in explosion-proof design according to ATEX. O O The explosion-proof design consists of the volume counter (intrinsically safe electrical apparatus) and the switching amplifier 13 (associated electrical apparatus). The type of protection intrinsic safety applies to this construction. O O The volume counter is installed in the potentially explosive atmosphere. O O The mounting of the amplifier 13 is carried out in the safe area. O O Volume counter and switching amplifier are electrically connected to each other. The switching amplifier evaluates the sensor signals and converts them to square-wave signals. O O Without switching amplifier, the volume counter must not be operated in the potentially explosive atmosphere. O O Cable lengths of up to m are possible between volume counter and switching amplifier. O O EDs for monitoring line breaks / short circuits, channel switching state and power supply are located on the switching amplifier.
