LCD Turbine Digital Flow Meter — 1″ BSP, Battery Powered
A compact battery-powered digital flow meter for dairy carts, diesel transfer and chemical dosing. 1" BSP fittings, ±1% accuracy, no power supply needed.
More product details
Overview
The LCD Turbine Digital Flow Meter is a battery-powered inline meter designed for the kind of fluid transfer jobs that come up daily on a dairy farm or in a workshop. Fit it to a calf milk cart and read off exactly how many litres each pen is getting. Plumb it into a diesel transfer line and stop guessing how full the ute tank is. Use it on AdBlue, urea or water lines where you need a number, not an estimate.
Key Features
- 1" BSP male thread inlet and outlet — drops straight into most dairy cart, diesel transfer and AdBlue plumbing
- ±1% accuracy, ±0.5% repeatability — reliable enough for batch dosing, mixing and transfer logging
- Dual totalisers — one resettable trip total plus one cumulative lifetime total on the LCD
- Litres or US gallons — switchable display, also reads pints and quarts
- Battery powered (2 x AA / 1.5V) — runs without mains, no wiring, fits any tank or cart
- PPS body — chemically resistant, suitable for milk, diesel, kerosene, AdBlue, urea and water
Built for on-farm fluid transfer
The unit screws straight in via 1" BSP male thread on both inlet and outlet, which is the standard fitting on most Australian dairy carts, fuel transfer pumps and chemical dosing setups. The turbine sensor sits inside the PPS body — a chemically resistant plastic that handles milk, diesel, kerosene, urea, AdBlue and most light chemicals without breaking down. Two AA batteries power the LCD; there’s no wiring loom, no transformer, no mains required. Mount it, calibrate it, and read it.
The display shows two totals at once. The top reading is your trip total, which you reset between jobs with the RESET button. The bottom reading is the cumulative lifetime total, which keeps ticking over so you can track service intervals or annual usage. The CAL button lets you fine-tune the calibration if your fluid viscosity or line pressure shifts the reading slightly off. Switch between litres, US gallons, pints and quarts on the same screen.
Note: this meter is marked NON COMMERCIAL on the face — it’s accurate enough for on-farm dosing, mixing, transfer and record-keeping, but it’s not legal-for-trade certified, so don’t rely on it for milk pickup invoicing or fuel resale.

FAQ
Will this digital flow meter work on a calf milk cart?
Yes. It’s the standard meter type used on dairy calf-feeding carts in Australia and New Zealand. The 1" BSP male threads match most cart plumbing. Fit it inline between the tank outlet and the dispensing wand, and you’ll read off litres dispensed per pen.
Can I use the same meter for diesel and AdBlue?
You can, but don’t switch fluids on the same meter. The PPS body and turbine handle both, but residual diesel will contaminate AdBlue and ruin a tank of urea solution. If you’re running both fluids on the farm, dedicate one meter per fluid.
Is it accurate enough to sell milk or fuel through?
No. The face is stamped NON COMMERCIAL and the meter isn’t legal-for-trade certified. It’s designed for on-farm metering, dosing, mixing and record-keeping — not for invoicing milk pickups or fuel resale. ±1% accuracy is fine for operational use but won’t satisfy NMI trade-measurement rules.
How do I calibrate it?
Run a known volume through (a 10 L jug is ideal), check the reading, then adjust using the CAL button until the display matches the actual volume. Recalibrate when you switch fluids or if the reading drifts.
What batteries does it take and how long do they last?
Two AA 1.5V alkaline batteries. Typical service life is 12–18 months under daily on-farm use. The LCD will fade before the meter stops registering, so swap the batteries as soon as the display dims.
