From the numbers to the part you quote.
Tenselo is a water-engineering calculator built around real jobs — size pumps, pipes, filtration and treatment, check the design against Australian and New Zealand practice, and hand over a clean report with the actual model, pipe class or dose rate. Built for irrigation designers and retailers; used across pumping, water treatment, aquaculture and civil.
Currently in private beta with Australian water professionals. Subscriptions open soon — register your interest and we’ll let you know.

Pick the job, not the formula
Calculators are organised by the work in front of you — size a mainline, pick a pump, check a water analysis — not by which equation they use. You do not need to know it is Darcy–Weisbach to size the pipe.
Enter what you actually know
Field inputs in the units you measure in. Where a figure is unknown, Tenselo carries a documented Australian default and tells you which one it used, so an estimate is never silently dressed up as a measurement.
Hand over a report, not a screenshot
Every result states the answer in plain English, names the actual model or pipe class to quote, and shows the inputs, method and assumptions behind it — as a branded PDF you can put in front of a client.
An answer you can act on
The part number, not just a number
Selectors pick from real supplier catalogues and name the model, so the answer is something you can order rather than a duty point you still have to shop for.
Plain English on every result
Each answer opens with a sentence a customer can understand. It is written for the person on the counter, and it is measured for readability, not judged by eye.
Australian and New Zealand practice
Methods follow AS/NZS and recognised industry references, with the assumptions and standards shown on the result rather than buried.
Reports you can hand to a client
A branded PDF with your own letterhead, the inputs you entered, the method used and the design that came out — ready to attach to a quote.
It says when it cannot answer
Where a duty falls outside what any listed product covers, Tenselo says so instead of quietly returning the biggest thing it stocks. A refusal you can see beats a wrong answer you cannot.
Built by people who sell this gear
Tenselo comes out of day-to-day Australian water and irrigation supply, not a generic engineering library.
Common questions
What is Tenselo?
Tenselo is an Australian water-engineering calculator suite for irrigation, pumping, water treatment, aquaculture, civil hydraulics and electrical work. It covers 349 calculators across 22 categories, and every result comes with a plain-English answer and a branded PDF report.
Who is it for?
Irrigation designers, pump and irrigation retailers, water treatment specialists, aquaculture operators, civil and hydraulic consultants, and the people on the counter who have to answer a customer's question quickly and correctly.
Can I use it now?
Tenselo is in private beta with a group of Australian water professionals. Subscriptions are not open yet. Register your interest and we will contact you when plans go on sale. Existing beta testers sign in at app.tenselo.com.au.
What does it cost?
Single-industry plans start at A$69 per month and the Complete Library is A$249 per month, with annual pricing at ten months for twelve. Team and enterprise options are priced on application. Prices shown are indicative until subscriptions open.
Which standards does it follow?
Methods are aligned to AS/NZS standards and recognised industry references, with manufacturer data taken from published datasheets. Every result shows the method and assumptions it used so the work can be checked.
Does it name real products?
Yes. Selector calculators pick from real supplier catalogues and name the model, pipe class or dose rate. Tenselo only ever names a brand you have asked it to consider, and every selection carries a note to confirm the exact model and trim with the manufacturer before ordering.
Is it Australian?
Yes. Tenselo is built in Australia for Australian and New Zealand practice, including local climate data, standards and supplier catalogues.
