Dwyer DR4146 | High Flow Glass Flowmeter | 0.1–2 GPM Water
Reading 0.1–2 GPM (0.5–8 LPM) of water, the Dwyer DR4146 high flow glass flowmeter gives straightforward flow indication at larger capacities. Its fused ceramic scale on the DR4146 carries integrated float guides.
- Direct reading water scale, 0.1–2 GPM (0.5–8 LPM)
- Permanently fused ceramic scale and integral float guides, 0.1–2 GPM water
- Easier reading via a 1.5x lens on the 0.1–2 GPM scale
- Safety blow-out rear panel; 200 psig (13.8 bar), 250°F (121°C); 0.1–2 GPM
- ±10% FS accuracy with 10:1 turn-down, 0.1–2 GPM

- Simplifies fluid flow indicator by offering a straight reading scale for air or water, particularly at greater capacity levels.
- Designed to endure the most demanding industrial applications, guaranteeing durability and dependability in difficult settings.
- Because the ceramic scale is permanently bonded, it is more durable and consistently provides precise readings.
- Has built-in float guides for optimal float performance and accurate measurement.
- makes use of a reflective plastic backdrop and a 1.5x magnification lens to provide more precise readings while minimizing eye strain.
- Has a safety blow-out rear panel to provide extra security and guarantee safety in the event of an emergency or pressure buildup.
