8. Perform a control of gas flow8.1. Perform a measurement of theoretical flow➢ Turn on the analyser.➢ Go to “Procedures” menu with up and down arrows then press OK.The analyser asks to select a customer : go to “OK” then press OK.The list of customers is displayed.➢ Select the customer then press OK.The list of boilers is displayed.➢ Select the boiler then press OK.“Procedure” screen is displayed.➢ Go to “Gas flow” with up and down arrows then press OK.A message indicating “Step 1 : Theoretical flow” is displayed.➢ Go to “Next” then press OK.“Theoretical flow” screen is displayed.➢ Specify the power capacity of the boiler in kW (data on the information plate of the boiler) : go to each number,press OK, use up an down key to increment or decrement the number then press OK to validate.➢ Make the same operation to select the standard : NF or CE.➢ Make the same operation to select the gas type : GAZ H, GAZ B, BUTANE or PROPANE.➢ Press the function key “OK” to validate.A message indicating “Step 2 : Real flow” is displayed.The theoretical flow is calculated according to a power capacity in kW of the boiler, the standard of the boiler (CE or NFstandard), the gas type (Gas H, Gas B, butane or propane) and according to a coefficient. Table below allows to calculatethis flow according to the power capacity :Standard GAZ H (19-21 mbar) GAZ B (25 mbar) Butane PropaneNF Pu/KW x 2,166 Pu/KW x 2,519 Pu/KW x 0,651 Pu/KW x 0,843CE Pu/KW x 1,927 Pu/KW x 2,241 Pu/KW x 0,579 Pu/KW x 0,7508.2. Perform a measurement of real flowThe measurement of the theoretical flow must performed previously.A message indicating “Step 2 : Real flow” is displayed.➢ Go to “Next” then press OK.“Start idx” is displayed.➢ Specify the start flow indicated on the gas meter : go to each number, pressOK, press up and down arrow to increment or decrement the number thenpress OK to validate.➢ Press the function key “OK” to validate..A message indicating « Step 2 : Wait : 2 min. » and a progress bar aredisplayed.➢ Wait for 2 minutes.It is possible to cancel this measurement : press OK.➢ Go to “Next” then press OK at the end of the 2 minutes.“End idx” screen is displayed.➢ Specify the end flow indicated on the gas meter : go to each number, press OK, press the up or down arrow toincrement or decrement the number then press OK to validate.➢ Press the function key “OK” to validate..A message displays the flow measurement result.24 Perform a control of gas flowRead a gas meter :Read a gas meter :Totalizer in m3 Totalizer in litersnetzerotools.comnetzerotools.com
