The MF3 target flow meter is built for the jobs other meters avoid: low flow velocities, very large diameters, dirty gases and viscous or fouling liquids. A Hall sensor measures the deflection of the target rod, so the sensor itself never touches the medium and there are no moving parts to wear.

The flow range can be changed simply by exchanging the target plate — no new meter is needed. Fully welded, dead-angle-free construction withstands 42 MPa, and integrated temperature and pressure compensation with the IAPWS-IF97 steam tables is available.

Key Features

Laser-sputtered sensor and fully welded lever structure; sensor isolated from the medium

FAQ

When should I choose a target flow meter?

For low-velocity, large-diameter or dirty media — for example sand-laden crude oil, associated water, dirty natural gas, resin, colloid and slurry flows where turbine or vortex meters foul or fail.

Can the MF3 range be changed on site?

Yes. Exchanging the target plate changes the measuring range without replacing the meter.

What temperatures and pressures can the MF3 handle?

Medium temperature -100 C to +450 C and pressure up to 42 MPa, depending on the version selected.
