• For highly viscous fluids Value indication, monitoring, transmitting, On/Off control and batch control in combination with different transmitters This sensor is specially designed for measurement or batch control of highly vis- cous fluids like glue, honey or oil. It allows an easy connection to transmitters like types 8025, 8611 and 8619 for more functionality. The design of this low flow sensor is based on the oval rotor principle. This has proven to be a reliable and highly accurate volumetric method of measuring flow. Exceptional repeatability and high accuracy over a wide range of viscosities and flowrates are features of this design. The low pressure drop and high pressure rat- ing make it suitable for gravity and pump (in-line) applications and many others. All sensors provide Open Collector NPN frequency output and frequency output on Reed contact via 1-meter 5-wire cable. Product variants described in the data sheet may differ from the product presentation and description. Type description Can be combined with Type 8077 © Christian Bürkert GmbH & Co.

The flowmeter can be installed in any orientation as long as the rotor shafts are always in a horizontal plane. Correct Incorrect The following installation conditions must also be observed: The pipe always has to be filled with fluid at all times near the device. The pipe design must be such that no air bubbles or cavitation can form within the medium near the device at any time. We recommend the installation of a 75 µm strainer as close as possible to the inlet side of the meter, to prevent damage from particles, Air purges can damage the appliance and should therefore be avoided. 6. Product operation 6.1. Measuring principle When liquid flows through the pipe, the rotors turn. This rotation produces a measuring signal in the associated Hall sensor. The rotation frequency of this signal is proportional to the flow velocity of the fluid. The volume of the fluid being transferred in this way is exactly determined through the sensor geometry. A conversion coefficient, specific to each meter size, enables the conversion of this frequency into a flow rate. The standard K factor depending on the meter size is available in the flowmeter’s operating instructions, see Type 8077 . To improve the measurement deviation, a device-specific K factor is given on the device label.
