Australian made Annubars

Exclusive – Annubars made and calibrated locally

Sizes range from DN50 to DN150 and are designed to operate in conjunction with our high accuracy digital Sprinkler flowmeters.

The probe stems are made from 316 Stainless Steel, and incorporate quality ball valves and fittings.

The probes and digital gauges are used in conjunction with a custom flow chart, which correlates differential pressure versus flowrate.

Each one is supplied with 4 laminated flow charts (in inches of mercury V flowrate – Litres/minute).
The charts are –
Medium steel pipe
Light steel pipe
Shed 40 steel pipe
Class B copper pipe

Annubars are 3/8″ diameter, single Mount type, and come with a sliding 1/2″ BSP S/S compression fitting.

Compatible with any standard sprinkler supply flowmeter that reads in inches of Mercury (in/Hg), however, we recommend our sprinkler flowmeters as they are vastly more accurate (within 1%- 0.3 in)/Hg) than old mechanical type gauges.

Annubar element sizes are –
DN50 (50mm)

DN65 (65mm)

DN80 (80mm)

DN90 (90mm)

DN100 (100mm)

DN125 (125mm)

DN150 (150mm)

and are available individually or as the full set of 7 annubars. See the video of the set here.
