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, following our installation guide. Standard threaded adapters on CPVC or UPVC, about 30 minutes per meter, no wiring. We send the guide on WhatsApp.
Site visit
Many installations can be assessed remotely from a pipe photo. A site assessment may be needed for larger lines or multi-flat projects.
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.

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 daily usage records to your phone, which helps identify unusual consumption sooner.
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 rated for 5 to 8 years of normal use. At battery end of life, the display stops and the meter is replaced using the existing compatible connections. Note the closing reading before removal and the new meter's opening reading after.

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.
Forty flats with one inlet each is 40 × ₹4,599 = ₹1,83,960, one time, nothing yearly. Orders of 20 or more get project pricing on WhatsApp. Or start with one meter on the sump inlet and add flats as the association agrees.
At your next reading. Wave has no connectivity, so there is no alert. Dhaara Pulse sends daily usage records to WhatsApp, which help identify unusual consumption sooner.
Yes, one meter per inlet, ₹9,198 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. ₹4,599 is the meter price; fittings and plumbing are extra.
The battery is sealed and rated for 5 to 8 years. At battery end of life, the meter is replaced using the existing compatible connections. Defects in the first year are replaced under warranty.
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 following our installation guide fits it in about 30 minutes with standard threaded adapters; we send the guide on WhatsApp. Many installations can be assessed remotely from a pipe photo; a site assessment may be needed for larger lines or projects.
Single units are available. Fit one on a flat or the sump line and read it yourself. If it does not do what we say, our return policy applies.
