GRYVOZE 2 Inch Digital Turbine Flow Meter
This 2 inch digital turbine flow meter from GRYVOZE features a clear LCD display for real-time flow rates, totals, and instantaneous data. With an accuracy of ±1%, it is suitable for measuring water, diesel, gas oil, gasoline, and other liquids. The unit supports multiple measurement scales and unit conversions (GPM, L, m³), enabling precise tracking across different applications. It is intended for sheltered environments and should be kept away from direct immersion, rain, and humidity for optimal performance.
FlowVis FV-2 Flow Meter with Check Valve
FlowVis FV-2 combines a flow meter with a built-in check valve and a velocity scale, allowing precise monitoring on 2″ Schedule 40 piping. It supports installation horizontally, vertically, or even upside-down, with minimal straight pipe requirements. The device claims high accuracy (≥98.1%), making it suitable for a range of water and liquid flow applications where a compact, reliable inline solution is desired.
2 Inch Digital Turbine Flow Meter NPT
This 2 inch digital turbine flow meter provides ±1% accuracy and supports various units (GAL, QTS, PTS, L, m³). It covers a flow range of 2.6–26 GPM (10–100 LPM) and supports a maximum working pressure of up to 6 Bar. The LCD display shows real-time flow, accumulated totals, and instantaneous flow, with a single count up to 99,999 and a total up to 29,999,999. It is suitable for measuring a range of liquids including water and fuels in sheltered environments.
Blue-White FLOWREAD R-320
The FLOWREAD R-320 is an acrylic 2″ flow meter designed for residential pool applications and 20–120 GPM flow ranges. It offers a straightforward installation on 2″ ID PVC piping and emphasizes an easy-to-read scale. The device is UV-stable with UV-printed scales on both sides for visibility in outdoor environments, making it a practical option for pool and spa water management where durable, long-term readability is essential.
Buying Guide: Key Purchase Considerations
- Accuracy and measurement range: Look for meters with ±0.5% to ±1% accuracy for precise readings across your expected flow rates. Verify the GPM/L ranges align with your system.
- Environment and durability: For outdoor or wet installations, choose IP-rated housings (IPX8 or higher) and corrosion-resistant materials. If used indoors, ensure humidity and temperature conditions won’t affect the electronics.
- Unit options and display: Ensure the meter supports your preferred units (GPM, L, m³, QTS, PTS) and offers a clear LCD or analog display, with real-time and accumulated flow data.
- Installation and orientation: Some meters allow horizontal, vertical, or inverted mounting. Consider the required straight pipe length and compatibility with existing fittings (NPT threads, flanges, or adaptors).
- Certification and safety: For potable water or regulated liquids, select meters with NSF/ANSI 61 or NTEP approvals. Lead-free construction is important for drinking water applications.
- Maintenance and power: Note battery life and auto-off features to minimize downtime. Replacement battery accessibility without disassembling the unit is a plus for installation convenience.
- Connectivity and scaling: Some meters offer cloud metering or data logging options. If remote monitoring is important, evaluate interoperability with gateways or AMR systems.
- Installation footprint and compatibility: Verify pipe size, inline mounting requirements, and whether a check valve is needed to prevent backflow in your system.
These considerations help balance durability, accuracy, and ease of use. The selected 2-inch meters cover a broad spectrum of applications—from pool and residential water monitoring to industrial liquid measurement—while offering robust construction and flexible installation in commonly encountered environments.
