- Depth scale for accur ate installation in existing pipes Usable in pipes fr om ½" up to 12" (DN 300) Easy installation under pr essure Int egrated Display S tandard and Heavy Duty version available This flowmeter series is made for the measurement of especially large flow rates and use the calorimetric measuring principle. A heated sensor element is cooled down by the gas flow. This cooling effect which depends on the flow velocity and the gas characteristics serves as a flow indication, the kind of cooling directly depends on the flow velocity and the kind of gas. This kind of mass flow measurement is independent of pressure and temperature. The flowmeter can be used for monitoring air supplies, but also qualifies for the measurement of other gases, see technical data. Type 8007 is available in two versions: - Standard - Heavy Duty (with a robust aluminium die casting electronics housing). In the Heavy Duty version the sensor is encapsulated in stainless steel. Product variants described in the data sheet may differ from the product presentation and description. Type descriptionCan be combined with Type 8007 © Christian Bürkert GmbH & Co.

For questions, please contact the responsible Bürkert facility. If the sensor is placed at the end of the Modbus syst em a termination is required. The sensors have an internal switchable termination. To use that the 6 fastening screws from the lid must be released and the internal DIP switch must be set to “On”. Please ensure that the connection plugs are still plugged and the gasket is installed correctly. Alternatively, a 120R resistor can be installed in the plug between pin 2 and pin 4.

Mounting options Note: In order to get the accuracy specified in the data sheets, the sensor must be inserted in the centre of a straight pipe section with an undisturbed gas stream. To obtain an undisturbed gas stream the sections in front of and behind the sensor must be straight, long enough and without any obstructions such as edges, seams, curves etc. Careful attention must be paid to the design of the outlet section as obstructions can cause counter-flow turbulences as well as turbulences in the direction of the flow. Installation in pipes at pressures > 10 bar r equires a high pressure safety device. 5.2. Installation not es Note: In order to maintain the accuracies specified in the data sheets, the sensor must be inserted centrally in a straight piece of pipe at a point with undisturbed flow. 45 x DN 5 x DN 35 x DN 5 x DN 20 x DN 5 x DN 15 x DN 5 x DN 15 x DN 5 x DN 15 x DN 5 x DN Control valve 2 × 90° elbow joint 3 dimensional 2 × 90° elbow joint 90° elbow joint or T-piece Pipe diameter expansion Pipe diameter reduction DN = pipe diameter Flow direction

Flow r anges depend on the version of Type 8007 (Basic, Extended, Maximum) and the internal pipe diameter. Type 8007 is adjust- able to different internal diameters through the mechanical depth scale. The sensor can be installed in any specified pipe siz e. The presetting of the sensor ex works applies to a 2" pipe (53.1 mm inner diameter). Each version is calibr ated to a flow velocity range: – Basic version up t o max. 92.7 m/s – Ext ended version up to max. 185 m/s – Maximum version up t o max. 224 m/s The 20 mA output corresponds to this highest speed, which in turn, depending on the pipe size, can be assigned a maximum flow rate, which in turn, depending on the pipe size, a max. flow rate can be assigned. Type 8007 without display: The scaling of the 4…20 mA output is carried out in the signal receiver, e.g. the PLC, using the measuring range table. Type 8007 with display: For the scaling of the 4…20 mA output, the specific pipe size (inner diameter) can be entered here via the display and the keys. Fur- thermore, the desired flow unit can be selected.
