Page 16: Installation And Commissioning
V-Flow Line Installation and commissioning General instructions Measuring instrument design In addition to the type code (see appendix) we require you to supply the following information for optimal design of the instrument: Medium Maximum flow rate For design without valve: Pressure in measuring cylinder ... - Page 17 V-Flow Line What is the purpose of standard liters and norm liters? In contrast to liquids, gases can be compressed, so it is important to know the density of the gas used. This in turn is dependent on pressure and temperature, i.e. if two quantities of gas are to be compared with one another, then the current pressure in the pipe and the current temperature of the medium must be known.

Page 21: Limit Indicator
V-Flow Line Limit indicator The V-100 variable area flowmeters can be equipped with a maximum of two limit indicators. The instruments with limit indicators have the following standard design: Minimum Switch Maximum Switch Initiator position Switching status Note: In case of power failure, the contact closes irrespective of the position of the float. For initialization, the float must first pass the initiator so that it is recognized by the initiator and the float position is defined. - Page 22 V-Flow Line Setting the limit indicator Remove the front glass (1) Unscrew both clamping screws (2) Position the limit indicator Tighten the clamping screws Fit the front glass For retrofit installation of a limit indicator the measuring glass must be removed.
- Page 23 V-Flow Line Minimum spacing for limit indicators To ensure that the limit indicators do not interfere with one another a minimum space must be complied with. Installed vertically in a measuring instrument: Measurement instruments adjacent to one another: A = Minimum 16 mm B = Minimum 6mm Areas of application Limit indicators only work with steel variable area flowmeters.
