The Poseidon water-cut meter features patented optical technology that delivers unmatched accuracy and reliability across 2 and 3 phase flow conditions. Multiple sensing points profile the water distribution in the pipe thus maintaining measurement accuracy in changing flow regimes and quasi-stratified flow.
The novel optical arrangement has been designed to prevent films and blockages on the optical windows to maintain accuracy at all times. The sensor has an automated diagnostic feature to detect and alert the operator of any optical issues and with multiple sensing points there is always measurement redundancy.
The probe form factor makes integration easy, quick and cost effective. The integrated temperature measurement allows for installation into existing thermowells reducing the barriers to entry and cost of installation.

The price is dependant on the configuration you require but we set out to develop and build the most cost effective water-cut meter in the Oil and Gas sector so please contact us for a quote.
Yes, the sensor has been tested in wet gas conditions up to 99.9% GVF.
Yes, the water-cut sensor has a Pt100 Class A temperature sensor integrated so you can replace an existing thermowell and get a water-cut measurement as well as temperature.
No, our multiple sensing points and novel analysis algorithms can calculate the water-cut in any flow regime.
