Page 2: Specification And Principle Of Operation
Specification and Principle of Operation Firegroove and Fireflange Type Introduction The Firesure flowmeter is a direct reading flowmeter, approved for use under the LPCB rules for automatic sprinkler installations. These meters have been approved for installation with gauge glass in the vertical position. There must be at least five diameters of straight pipe upstream and downstream of the orifice plate. -

Page 5: Connecting The Bypass
Connecting the Bypass Indicator Remove red plastic stop and retaining rod from top block. Remove retaining screw and assemble restrictor and bleed assembly to indicator top block with retaining screw in place. Rear view of indicator piping as supplied suitable for connection to main orifice carrier for horizontal flow right to left or vertical flow upward. -
Page 6: Installation In-Line
Installation In-Line White a) Ensure direction arrow is consistent with viewed direction of flow and position Fireflange between pipeline flanges concentrically. Concentricity can be achieved by ensuring the carrier outside diameter is central to the fixing bolts. b) Firegroove type should be fitted with approved couplings suitable for groove cut joints. c) When fitting Fireflange type, ensure that any sealing gaskets do not obstruct the pipe line or carrier bore. -
Page 7: Operation
Operation Flow Test Ranges The Firesure flowmeter is designed to test that the automatic sprinkler installation meets the required flow rate needs. Each size of flowmeter meets a particular duty as shown below. Size Flow Range 150-700 300-1600 500-3500 900-7900 2000-15000 Flow Testing and Reading Open... -
Page 8: Maintenance
Maintenance Changing Glass Indicator In case of breakage a glass tube indicator would be required. Refer first to the black printed Firesure model number F3/- on the carrier label or tube before ordering a replacement. NOTE: This model uses BLACK scaled tubes. These should not be replaced with RED scaled tubes which are used for the extended indicator model (Firesure X).
