Mechanical Installation. Badger Meter RVL Tube, RVL Wafer, RVL Inline

Below you will find brief information for Vortex Shedding Flow Meter RVL Inline, Vortex Shedding Flow Meter RVL Wafer, Vortex Shedding Flow Meter RVL Tube. The RVL series meter uses vortex-shedding technology for repeatable flow measurement accurate to ±1 percent of full scale. The meter has no moving parts, and any potential for fluid contamination is eliminated by the corrosion-resistant all plastic construction. The meter includes a compact two-wire (4…20 mA) or three-wire (0…5V DC or pulse) transmitter, contained within a conveniently replaceable plug-in electronics module. Units can be re-calibrated and the meter output span can be reprogrammed in the field.

Frequently asked questions

The minimum flow rate for the RVL Inline meter is 0.6 GPM for the 1/4 inch model and 1.3 GPM for the 1/2 inch model.

The operating temperature range for the RVL Inline meter is 70°F to 203°F.

To clean the flow tube, run hot, up to 160°F, soapy water into the downstream end of the flow tube. Dislodge large objects jammed against the bluff body by lightly tapping the upstream end of the flow tube against a firm surface.

The accuracy of the RVL series meter is ±1% of full scale for 4…20 mA or 0…5V DC output and ±2% of full scale for frequency pulse output.

The RVL Wafer series transmitters are designed with wafer style flow bodies, that mount easily between standard ANSI style pipe flanges. Install the meter where pipe vibration is minimal. Use the upstream and downstream piping requirements shown in "Piping Requirements" on page 6. Do not use upstream valves to control flow rate. Always keep upstream valves fully open.
