A flow meter for large pipes that goes in through a ball valve, so it is fitted and withdrawn without stopping the flow. It has no moving parts and causes almost no pressure drop, on any conductive liquid from 30 µS/cm.
The probe mounts through a ball valve saddle and is inserted and removed under pressure. The main stays in service while the meter goes in, and again when it comes out for inspection.
The probe length follows the pipe diameter. The same meter covers a DN100 branch and a DN3000 main, where an inline meter would be a different instrument at every size.
Measurement is bidirectional, and the full-scale velocity is adjustable from 1 to 10 m/s to match the line.

The probe is inserted to half the pipe diameter up to DN400, and to a quarter of the diameter above that.

| DN ≤200 | 630 mm |
| DN250-DN400 | 730 mm |
| DN401-DN1200 | 830 mm |
| DN1401-DN2000 | 1030 mm |
The sensor is a standard Modbus device. What it is connected to decides what the reading is worth.
The RS485 output connects to a Genesis controller alongside every other Modbus sensor on the site. Each device has its own address, and each reading is filed against its own location.
The controller sends readings over 4G-LTE on battery, solar or a DC supply. Through an outage it holds them and sends them in order when the link returns.
Charts, threshold alerts to the right person, export to Excel, and a REST API for your own systems.
The output is standard Modbus RTU, so the sensor also reads into any PLC or controller that speaks it.
No. The probe mounts through a ball valve saddle and is inserted and withdrawn under pressure.
Electrically conductive liquids, from 30 µS/cm. Oils, fuels and demineralised water are below that and cannot be measured this way.
No. The transmitter needs 85 to 250 VAC or 20 to 36 VDC and draws up to 20 W. The Genesis controller that reads it can run on its own battery and report over cellular.
It is specified at ±1.5% of reading at 1 m/s and above. An inline electromagnetic meter is tighter, and is the right choice where the pipe is small enough to take one and the line can be cut.
