One meter per inlet. Here is what that means in your building.
Wave measures the water that passes through it. Check both: the right meter size and the number of supply inlets. Three common layouts:
Who installs it
A qualified plumber you arrange, following our installation manual and guidance videos. Standard threaded adapters on CPVC or UPVC, about 20–30 minutes per meter, no wiring. We send the manual and videos on WhatsApp.
Site visits
We do not survey or visit sites. Send a pipe photo on WhatsApp and we help you check the size; your plumber handles the fitting.
Where we are
Designed and built in Hyderabad. Shipped across India in 1–2 weeks. Support on WhatsApp, Mon to Sat, 9 to 6.
Mechanical vs ultrasonic
Your mechanical meter has moving parts. Water has air.
Tanker fills and intermittent supply push air through the line. An impeller spins on air and registers it as water; it misses slow drips, and its gears drift as they wear. Wave measures with ultrasound. Nothing spins.

Modern measurement. No moving measuring parts.
How ultrasonic measurement works
Sound waves measure the flow. Nothing spins.
Two transducers in the meter body send an ultrasonic pulse along the pipe, one with the flow, one against it.
The pulse travelling with the water arrives slightly sooner. The time difference tells the meter how fast the water is moving.
Flow is totalled over time and shown on the LCD as volume in cubic metres.
Reading the meter
Measure usage between any two readings.
Record the meter reading at the beginning and end of a period. The difference shows the volume of water that passed through the meter during that period. One cubic metre is 1,000 litres.
ExampleVolume
Beginning of period125.000 m³
End of period137.500 m³
Consumption during period12.500 m³ · 12,500 L
A leak shows up the same way: a reading that moved when nobody used water. You see it at your next reading. Pulse sends a daily water receipt to your phone, so you can review use every morning instead.
Battery · Warranty · Lifespan
“What happens when the battery dies?” Here is the straight answer.
The battery is sealed inside the meter and is not user-replaceable. It is expected to last 8 years under normal conditions: an expectation, not a warranty. At end of life the display stops, and the battery is replaced at our factory for a charge; you do not have to buy a new meter. Note the reading before the meter is removed.

Not for: tank level, pump control or water quality. Wave is a flow meter. It tells you how much water passed a point in the pipe, nothing else.

Questions customers ask us
Your questions, in your words.
These are the questions we hear most on the phone, answered the way we answer them on the phone. If yours is missing, ask.
In a tower, start with the sources and distribution: one meter on the sump inlet and on each tanker, borewell and tower line, and add flats as the association agrees. Per-flat metering works where each flat has its own inlet: 40 × ₹4,999 = ₹1,99,960, one time, nothing yearly, though in a tower it means more plumbing. Orders of 20 or more get project pricing on WhatsApp.
At your next reading. Wave has no connectivity, so there is no alert. Dhaara Pulse sends a daily water receipt to WhatsApp so you can review use every morning, though it sends no leak alerts either.
Yes, one meter per inlet, ₹9,998 per flat. Add the two readings. If flats share a riser with no per-flat branch, meter the tower or sump inlet instead; we will tell you honestly if per-flat metering needs re-plumbing.
None. No subscription, SIM, app or recharge, for one meter or a hundred. ₹4,999 is the meter price; fittings and plumbing are extra.
No. The battery is sealed and expected to last 8 years under normal conditions, an expectation rather than a warranty. At end of life it is replaced at our factory, for a charge. Defects within the warranty (12 months from delivery, or 13 from invoice if earlier) are repaired or replaced.
No. Wave is a flow meter: it tells you how much water passed through the pipe. It does not measure tank level, control pumps or test water quality.
A qualified plumber you arrange fits it in about 20–30 minutes with standard threaded adapters, following our installation manual and guidance videos; we send both on WhatsApp. We do not visit or survey sites: send a pipe photo and we help you check the size.
There is no demo or trial programme. Single units are a normal purchase, so you can fit one on a flat or the sump line and read it yourself before a larger order. A fitted meter is not automatically returnable; a return request is reviewed case by case.
₹4,999 including GST for 15 mm, 25 mm and 50 mm alike. Fittings, unions and your plumber are extra.
Hyderabad; the meters are built in our own Legal Metrology approved facility. We ship across India in 1–2 weeks and support on WhatsApp, Mon to Sat. Installation is by your local plumber.
Ultrasound measures the water, so nothing spins or wears. A digital display shows the total in m³. You read it, subtract the last reading, and that is the consumption. That is the whole product.
Yes. Message us on WhatsApp and we send the installation manual and guidance videos, no form to fill.
No SIM, no Wi-Fi, no app and no WhatsApp water receipts. Those belong to Pulse. Wave works with nothing but its battery.
Not Wave; it has no output. For integration or custom requirements, speak to the Pulse team.
ISO 4064 Class 2 and OIML R49 model approval, manufactured in a Legal Metrology approved facility. Certificates are supplied on request for tenders and compliance files.
Acceptance depends on the application and the relevant authority's requirements. For internal cost-sharing in a society or between tenants, the readings are what you need.
