STAUFF Flowtell SFF Sight Flow Meters – Oil & Water, 0.5 to 550 L/min, 3/8" to 1-1/2" BSPP

The Flowtell SFF series from STAUFF is the quickest way to put a set of eyes on your hydraulic or water flow. It is a fully mechanical variable-area sight meter that plumbs straight into the line and reads flow directly off the scale – no power, no sensors, no setup. Pick your fluid, port size and flow range from the dropdown and it is on its way from Australian stock.

Ways to buy your flow meter:

• Off the shelf below – 31 Flowtell variants: oil or water calibrated, aluminium or brass bodies, 3/8" to 1-1/2" BSPP.
• Need test-point connections, a pressure gauge or a load valve with it? See our flow test kits linked further down – we build and stock complete kits.
• Digital readout or high pressure testing? Step up to the STAUFF digital hydraulic testers (up to 480 bar, 800 L/min) linked below.
• Unusual fluid, flange mounts or a range you cannot see? Call us – we can quote factory-built options.

What is in the optional add-on kits

Every kit component is a genuine catalogued part with its own SKU, so you know exactly what arrives in the box and can reorder any piece individually later.

Installation kits – plumb the meter into the line and load the circuit for testing:

Pressure gauge kits – read pressure right at the meter through a gauge-port test tee:

Pick the kit that matches your meter’s port size – the dropdown labels carry the size. Not sure? Call us.

How to choose

• Match the fluid first: O-models are scaled for hydraulic oil, W-models for water – a meter on the wrong scale reads wrong, every time.
• Size by flow, not by port: pick a range where your normal flow sits in the middle two-thirds of the scale – that is where a variable-area meter is most readable and most accurate.
• Then check the port: all Flowtells are BSPP female. If your line size and the right flow range do not line up, bush down the ports rather than over-sizing the meter.
• Aluminium vs brass: aluminium is lighter and cheaper for oil; brass suits water systems and mixed-fluid workshops.
• Adding an installation kit? Match the kit size to your meter’s port – the kit sizes are labelled. Not sure, call us.
• Not sure between two ranges? Call us with your pump displacement and RPM – we will size it in a minute.

Technicians Advice

A sight flow meter is the cheapest diagnostic tool you will ever plumb into a machine. Fit one permanently on the return line of a power unit and you can spot a worn pump months before it fails – flow at working pressure and temperature tells you what a pressure gauge cannot.

When you are sizing one up, remember the scale is calibrated for the viscosity of the fluid on the label: hot thin oil will read slightly differently to cold thick oil, so treat the reading as a healthy-or-not indicator rather than a lab instrument, and always compare like-for-like (same temperature, same duty) when you are trending a machine over time.

If you are flow-testing under load rather than just watching flow, you want a tester with a load valve – that is where our flow test kits and the STAUFF digital testers come in.
