1 8070 Positive displacement flowmeter for continuous flow measurement High accuracy Medium with high viscosity Mounting and dismounting of the electronics by a quarter-turn Connection to Bürkert devices in remote versions Type 8070 can be combined with... Type 8025 Type 8025 Konti-Dos Type 8611 Type 2712 (8630) PLC Flow transmitter remote version Batch control system econtrol Universal controller Continuous TopControl system The positive displacement flowmeter for continuous flow measurement is especially designed for use in highly viscous fluid like glue, honey or oil. It is made up of a compact sensor fitting (S070) with integrated oval rotor and an electronic module (SE30) with pulse signal (Hall transducer), quickly and easily connected together by a Quarter-Turn. The Bürkert designed fitting system ensures simple installation of the devices into all pipes from DN15 to DN100. The flowmeter produces frequency signal (pulse), proportional to the flow rate, which can easily be transmitted and processed by: - a Bürkert remote transmitter (Type 8025/ ) - a batch control system 8025 Konti-Dos - a PLC Technical data General data Compatibility with sensor fittings S070 (see corresponding data sheet) Materials Housing, cover PC Cable plug PA Wetted parts materials Sensor fitting Aluminium, stainless steel (316F/1.4401) Rotor PPS, aluminium, stainless steel (316F/1.4401) Shaft / Seal Stainless steel / FKM or FEP/PTFE encapsulated Electrical connection Cable plug EN Connection cable max. 1.5 mm 2 cross section; max. 50 m length, shielded (for pulse sensor version) Complete device data (sensor fitting + electronic module) Pipe diameter DN15 to DN100 Measuring range Viscosity > 5 cps Viscosity < 5 cps Medium temperature max.

This connection is made by means of a Quarter-Turn. Quarter-Turn Technology SE In a 3-wire system (transistor output), the signal can be displayed or processed directly. The output signal is provided via cable plug according to EN S070 When liquid flows through the pipe, the rotors turn. This rotation produces a measuring signal in the transducer. The frequency and amplitude are proportional to the flow. A conversion coefficient (K factor, available in the instruction manual of the sensor fitting S070), specific to each pipe (size and material) enables the conversion of this frequency into a flow rate. Two electronic module versions with frequency output are available: - with one pulse output (either NPN or PNP transistor output). An external power supply of V DC is required. It is designed for connection to any system with open collector NPN or PNP frequency input. - with one pulse Low Power output (NPN transistor output). An external power supply of V DC is required. Can only be connected to separate versions of flow transmitters Type 8025/8032, to ma module Type 8023 or a universal controller econtrol Type Installation The sensor fitting can be installed in any orientation as long as the rotor shafts are always in a horizontal plane (see figures to the right) and the flow of the fluid is in the direction of the arrow marked on the body. Correct The pipe must be filled with liquid and free from air bubbles. Avoid air purge of the system which would cause damages and to prevent damage from dirt or foreign matter, we strongly recommend the installation of a 250 m strainer as close as possible to the inlet side of the meter.

Type 8070 Type 8072 Type 8075 Type 8076 Positive displacement flowmeter Positive displacement flowmeter Positive displacement flowmeter Positive displacement flowmeter This positive displacement sensor fitting is specially designed for flow measurement and/or batch control of highly viscous fluids like glue, honey or oil. This measuring element must be associated to an electronic module SE30, SE32, SE35, SE36 with hall sensor principle only, quickly and easily connected together by a Quarter-Turn. The design of this fitting 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 that design. The low pressure drop and high pressure rating make it suitable for both gravity and pump (in-line) applications.
