Waterproof 2 Inch Water Flow Meter — GRYVOZE Store
Best for outdoor installations and harsh environments. This 2 inch meter features an IPX8 waterproof and outdoor-ready sealed aluminum alloy housing, making it suitable where moisture, rain, or splashes are common. It supports high-capacity liquids like water and fuel and provides accurate readings with ±1% accuracy for dependable data. An LCD screen includes energy-saving software, auto-off after 10 minutes, and a low-battery alert for easy replacement without detaching the unit.
Who it’s best for: facilities needing reliable outdoor metering with durable housing and long standby battery life. Choose this if you operate in wet or outdoor environments and require precise flow data for quantities like water, diesel, or fuel oil. Caution: LCD screen may dim in bright sunlight; confirm installation orientation so the meter remains easily readable.
DAE MJ-200 2″ NTEP NSF61 Potable Water Meter
Best for potable water systems requiring regulatory approvals. This meter carries National NTEP approval for accuracy and repeatability, with NSF certification meeting ANSI/NSF 61 for material safety and ANSI/NSF 372 for lead-free plumbing. It’s designed for horizontal inline mounting with the dial facing upwards and is suitable for standard water distribution contexts. It does not include pulse output, which may influence how you integrate it with remote read systems.
Who it’s best for: building managers and plumbers needing certified potable-water metering for compliant installations. Choose this if you require NSF/ANSI 61 and NTEP compliance. Caution: Not recommended for pit installations or use in vertical-downward or upside-down configurations without the alternative model guidance.
2 Inch Digital Turbine Flow Meter — GRYVOZE Store
Best for sheltered environments requiring precise digital readouts. This meter provides an LCD display with real-time flow rates and totalization. It has a high accuracy of ±1% and supports measurement for water, diesel, gas oil, gasoline, and other liquids. A notable limitation is that it is not waterproof and should be kept dry, avoiding exposure to rain, humidity, or immersion. The unit offers straightforward single-count and total counts, helpful for straightforward billing scenarios.
Who it’s best for: facilities in sheltered or indoor locations where the environment is controlled and protection from moisture is essential. Choose this if you want a clear LCD readout and simple integration with non-outdoor systems. Caution: not suitable for outdoor or wet installations.
2 Inch Water Flow Meter Thread Turbine Flowmeter — GoHz Store
Best for versatile sizing and multiple fluid types. This turbine flow meter offers an optional 1, 1.5, 2, 2.5, and 3 inch port size and is designed for a wide range of fluids including diesel, fuel, and water. It uses a digital display to show real-time flow data, enabling easy monitoring. A limitation is that some versions are not specified as waterproof, so use in dry or sheltered environments is recommended. The meter supports multiple units for easy conversion (QTS, PTS, L, GAL, m3).
Who it’s best for: operations needing flexible port sizing and multi-fluid compatibility in controlled environments. Choose this if you require a meter that can be adapted to different pipelines and unit preferences. Caution: verify environmental protection (waterproof rating) before outdoor installation.
DAE MJn-200 2″ Water Meter — Pulse Output + Couplings
Best for remote monitoring and tenants’ billing needs. This meter supports horizontal inline mounting with dial facing upwards and can integrate with cloud metering solutions (a second picture shows the CC2030 gateway). It also mentions compatibility with CO-10 pulse counters and AMR options for remote reading across multiple meters. The data flow enables real-time usage tracking and monthly billing reports. A caution: cloud metering requires additional hardware and setup, and the data path depends on network connectivity.
Who it’s best for: property managers and facilities teams seeking remote readouts and automated billing across meters. Choose this if you want cloud-based monitoring and alerting for abnormal usage. Caution: ensure network readiness and consider additional investment for remote-reading hardware.
Buying Guide
- What is the intended environment? Outdoor, indoor, or sheltered spaces require different IP ratings and housing materials. For outdoor wet conditions, prioritize IPX8-rated enclosures.
- Is potable-water certification necessary? If you’re metering drinking water, NSF/ANSI 61 and possibly NTEP approvals may be required by local codes.
- Do you need remote readings? Pulse output, cloud metering, or AMR options enable remote monitoring and billing. Consider compatibility with your existing data systems.
- What unit formats are needed? Ensure the meter supports the units you use (QTS, PTS, L, GAL, m3) and has a clear display for daily operation.
- What is the installation orientation? Some meters specify horizontal inline mounting, while others tolerate vertical orientations with appropriate guidelines. Confirm installation position before purchase.
Frequently Asked Questions
- What is the typical accuracy? Many meters offer ±1% accuracy for reliable flow data in industrial contexts.
- Can these meters measure multiple liquids? Several models are designed for water, diesel, fuel oil, gas oil, gasoline, and similar liquids, but ensure chemical compatibility with the meter’s materials.
- Do these meters require batteries? Some models include LCD displays with battery power and low-battery alerts; others use different power options.
- Is remote monitoring optional? Yes, several meters offer cloud metering or pulse-output options to support remote readings and billing.
- Are NSF/ANSI certifications necessary for every installation? Not always, but for potable-water installations in regulated settings, they are often required or highly recommended.
- Can meters be installed in pits or vertical orientations? Check each model’s mounting instructions, as some are not suited for pit installations or vertical-downward configurations.
