(Was Model 31802V), (Was Model 31802VFL), (Was Model 31802VSP)
Meter Type
Economy Water Flowmeter, turbine type, battery powered that displays rate of flow and totals.
How It Works
Magnetic pulses are picked up by a coil. The computer converts the pulses into a flow rate and totals.

Application Notes
- Saturated Steam Service: Not acceptable
- Potable Water: Yes – NSF Approved
- Vacuum Service: Not acceptable
- Gaseous Service: Not acceptable
- General Non-Suitable Services: Not acceptable for petroleum products, deionized (DI) or ultra-pure water applications. Not suitable for medias with varying viscosities.
- Installation: Do not allow media to freeze inside meter. Installation to metal connections is not recommended. Limit display’s exposure to sun.
- Corrosion: Before ordering, verify all materials of our flow meters are compatible with the service media(s), intermittently used cleaners, the environment, and cleaning processes in conjunction with the temperatures and pressures of the application(s) and future applications. John C. Ernst Co. does not make chemical compatibility recommendations. Compatibility is the responsibility of the user and/or specifying party.
