Flowatch HS multiphase flow meter with high-speed gamma densitometer for well testing by Pietro Fiorentini
Multiphase Flow Meter

Flowatch HS High Speed Multiphase Flow Meter for Well Testing

The Flowatch HS (High Speed) is a multiphase flow monitoring device designed for well testing applications. It fulfills the essential requirements of well testing as a simple device to track individual phase outputs from production streams. This meter builds upon over 15 years of proven field performance, enabling high accuracy performance levels through radioactive source technology.

Frequently asked questions

What does HS mean, and how does the Flowatch HS reach high accuracy?

HS stands for High Speed. The Flowatch HS uses a radioactive source, a Cs-137 gamma source of 5 mCi, in a patented fast gamma densitometer to measure mixture density. This gives typical water cut uncertainty of 2 percent at 0 to 60 percent GVF and covers up to 98 percent GVF. Dose level is stated as 1.05 µSv/h at 1 m.

When should I choose the Flowatch HS instead of the Flowatch 3i?

Choose the Flowatch HS when wells run above 92 percent GVF, up to 98 percent, or when you need its tighter uncertainty, and when your site can manage the documentation and handling a radioactive source requires. If a source-free meter is needed, the Flowatch 3i or Totem are the alternatives. Flowatch HS sizes start from 1.3 inch.

Can Pietro Fiorentini support the Flowatch HS in the GCC?

Yes. Pietro Fiorentini Saudi Industry in Al Khobar supplies and supports the Flowatch HS for well testing in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain and Oman. Contact us with your production data and site requirements, and we will propose a configuration and quotation.
