Heinrichs Messtechnik GmbH Applications The flow meter is suitable for the measurement of the flow of liquid and gaseous products in pipes. It displays the current flow in volume or mass per unit time. Applications: Measuring the flow of liquid and gaseous products in pipes as well as dosing, superimposing, monitoring, regulating and the controlling of them.
Heinrichs Messtechnik GmbH Operational mode and system design K09 Float principle: The product flows vertically through the meter from the bottom to the top. The height of the float in the measuring tube is a measure of the flow quantity. The float is in equilibrium between the buoyant force of the flowing medium and the counteracting force of gravity on the float.
Heinrichs Messtechnik GmbH Input Measured variable: Volume flow Measuring ranges: (lower-range and upper-range values) Measuring span water 20 °C: Smallest measuring range: 0.02-0.25 l/h water Largest measuring range: 10-100 l/h water Measuring span air 20 °C, 1.013 bar abs. Smallest measuring range: 2-20 Nl/h air Largest measuring range: 300-3000 Nl/h air Measuring /regulating range for K09-..V / N Span: 10-100 %...
Heinrichs Messtechnik GmbH Conditions of use The VDI/VDE guidelines must be observed. The devices can be used for: liquid products that are sufficiently free-flowing, are free of solids, do not bond or do not tend to settle. gases with linear flow behaviour and an adequate inlet pressure. V/N(optional differential pressure regulator) The minimum differential inlet and outlet pressures must amount to 350 mbar.
Heinrichs Messtechnik GmbH 7.1.3 Requirements for installation dust environments a) In certain circumstances, the non-metallic parts of the sensor may generate an ignition-capable level of electrostatic charge. Therefore, the user/installer shall implement precautions to prevent the build-up of electrostatic charge, e.g. locate the equipment where a charge-generating mechanism (such as wind-blown dust) is unlikely to be present.

NAMUR recommendation NE 21 Product standard: EN 60947-5-2 Fluid conditions 7.3.1 Fluid temperature ranges without limit switch -20 °C to + 100 °C with limit switch -20 °C to + 70 °C Risk of breakage due to frost 7.3.2 Fluid pressure limit...
Heinrichs Messtechnik GmbH Construction details Design/dimensions K09 The meter consists of a conical measuring tube made of borosilicate glass, with a vertical movable float made of stainless steel or glass. The measuring tube is mounted vertically in the device fitting, which possesses two process connections, arranged perpendicularly to the measuring tube, on its rear.
Heinrichs Messtechnik GmbH IMPORTANT COMMISSIONING NOTES The installation of a valve before the inlet and outlet of the instrument shall be avoided Initial operation / start-up of the process only with opened control valve When operating with gas the inlet pressure shall be increased slowly to avoid strong pressure ...
Heinrichs Messtechnik GmbH Electrical connection for limit switch (option) with cable length of 2 m The limit switch (ring form) can be adjusted up and down the measuring tube. It is fixed via two screws (1) at the back wall of the instrument. Adjusting of the contact: (2) Contact on measuring tube...

Heinrichs Messtechnik GmbH If grounding cannot be guaranteed via the process connections (e.g. plastic process connections), the flow meter must be connected to the local ground potential via the flanges. This connection only ensures electrostatic grounding of the device and does not meet the requirements for equipotential bonding.
Heinrichs Messtechnik GmbH 12 CE marking The measuring system meets the statutory requirements of the following EU directives: 2014/34/EU (ATEX) Equipment for Use in Potentially Explosive Atmospheres 2014/30/EU (EMC) Electromagnetic Compatibility. With respect to the Pressure Equipment Directive 2014/68/EU, the devices fall within the scope of application of Article 4, Paragraph 3, and therefore requires no CE marking in accordance with this directive.
Heinrichs Messtechnik GmbH 16 Safety instructions 16.1 Intended use The K09 variable-area flow meter may be used only for flow measurements of fluid and gaseous media. The manufacturer shall not be liable for damage which results from improper or unintended use. When dealing with an aggressive medium, the material durability of all wetted parts is to be clarified.
Heinrichs Messtechnik GmbH 18 Maintenance If you use the meter in the intended manner no special maintenance is required. However, the variable area flow meter should be checked in the context of the routine maintenance of the facility and the pipelines. Special attention should be paid to dirt, corrosion denudation, mechanical wear as well damage to the glass cone.
Heinrichs Messtechnik GmbH 18.1.3 Depiction of the dis- and reassembly Clamping ring Caution! The shaft packing of the valve must be readjusted during the life cycle. This requires tightening of the thrust piece (1) Loosen grub screw (2) M4x8 with hexagon 2mm and remove valve knob (3).
Heinrichs Messtechnik GmbH 19 Returning devices for repair and service Note: In accordance with the applicable waste disposal legislation, the owner/client is responsible for the disposal of special waste and hazardous materials. Consequently, all devices sent to Heinrichs Messtechnik for repair must be free of any hazardous materials.
