Kytölä Model MP-O Metal Tube Variable Area Flow Meter

MP-O is a variable area flow meter with a flow tube, connections and float made of AISI 316L stainless steel. It is used on low-flow liquid and gas lines at chemical, petrochemical and energy plants, at pressures and temperatures that a glass or plastic body cannot withstand.

MP-O features

• Pressure up to 235 bar in the valveless design; temperature up to 100 °C on the model with alarm and 150 °C on the model without alarm.
• For water, a lowest range of 1-10 L/h and a highest of 40-400 L/h; for air, ranges from 60-320 to 1000-12000 NL/h can be selected.
• Indicator body aluminum (316L optional), window polycarbonate (borosilicate glass optional).
• Seal Viton; EPDM offered as a special design.
• 1/4 or 1/2 inch G/NPT connection; ATEX (II 2GD c TX) version available.
• Accuracy ±5% of full scale, weight approximately 700 g.

Choosing MP-O

The MP-W model with alarm sensor and a wider temperature range is in the same family. Because of the metal tube, the flow cannot be seen directly, so indicator and scale selection relies on calibration according to fluid density.

Tetra reviews the fluid, pressure and measuring range and recommends the right scale and seal combination. Leak checks after mounting and seal and float maintenance that may be needed over time are done on site; parts are easy to dismantle.
