Page 8: Corrosive Gases
Corrosive Gases The operator is solely responsible for the safe operation of the system and takes precautions to protect the environment and/or persons in the event of leaks. The instrument may only be operated with the gases for which the instrument has been designed and specified. -
Page 9: Information On The Type Plate
Information on the type plate The type plate on the Q-Flow is located on the back of the carrier plate and must not be removed. Example: Key: Serial number Order number or subject of the customer 05/17 Date of manufacture, month/year Typ: Specification according to type code (standard devices only) Medium, measuring range, unit, pressure, temperature &... - Page 10 Operating principle of the variable area flowmeter The measuring instrument works according to the float measuring principle The measuring unit consists of a tapered graduated precision glass measuring cylinder in which a ball float can move freely up and down. The medium flows through the vertically-aligned measuring cylinder from the bottom upwards The float positions itself so that the buoyancy force A acting on it, the form resistance W and its weight G are in balance:...

Page 18: Installation And Commissioning
Installation and commissioning Installation instructions The flowmeters may only be installed and commissioned by qualified personnel. The pipeline must be free of particles and moisture before installation of the measuring instrument. Please flush it before mounting the instrument in the pipe. ... -
Page 19: Disassembly And Maintenance
Disassembly and maintenance Important instructions Please close the gas supply, flush the pipes and then close any shut-off valves. Make sure that the line is depressurized and that no dangerous gas can enter the environment. You can then start removing the meter. Only use suitable tools for this purpose. The removal and installation of the measuring instruments may only be carried out by qualified personnel. - Page 20 Panel mounting Q-Flow For mounting, the panel opening must be prepared according to the diagram. Screw the two mounting brackets onto the instrument as shown. Screw the setscrew supplied into the connector and insert the instrument into the aperture from the front.

Page 21: Maintenance
Maintenance When used correctly, variable area flow meters from Vögtlin Instruments AG do not require any maintenance. Pollution The following symptoms indicate pollution: The set value can no longer be reached – the control valve is probably soiled The measured value increases although the effective flow rate has not been changed - measuring tube is dirty. - Page 22 Appendix Dimensions Q-Flow Instruction Manual Version Page Q-Flow qflow_D5_0 © Vögtlin Instruments GmbH WWW.TEESING.COM | +31 70 413 07 50...
