OVAL FLOWPET-5G Positive Displacement Flowmeters

In principle, the flowrate in a positive displacement (PD) flowmeter is calculated from the number of revolutions of a rotor activated by the energy of fluid. Generally, these flowmeters offer high accuracy measurement and are suitable for totalling the flowrate.

The OVAL FLOWPET-5G PD flowmeter is primarily intended for use in boiler feed water and fuel oil metering applications. OVAL says that high accuracy and long service life along with ease of use make this industrial meter suitable as a dedicated tool for heat control.

It has a high accuracy of ±0.5% RD for oil and ±1.0% RD for water, and the flow and instantaneous flow is displayed on a dirt-resistant digital LCD display with touch of mode select switch and a large 14 mm character height. The display can be tilted for better visibility (±75°).

The electronic register-equipped models have an internal, easily replaceable battery with a typical life of years, eliminating the need for an external power source. An external power source is recommended for pulse output models.

The factored pulse width is variable in 1 ms steps with the front panel buttons (adjustable from 1 to 999 ms). Simulated outputs are available for pulse output models, and the pulse and analog output can be simulated at any flow rate for loop tests. A 4–20 mA analog output is also available.
