The unit includes an easy-to-read LCD display and a one-touch control button, allowing four measurement modes to track Flow, Consumption, Average, and Total usage. This setup is particularly suited for RV water tank filling, garden irrigation, and nozzle spraying, where quick mode switching ensures you can monitor real-time flow or total usage at a glance.
Mode options include:
- FLOW: Real-time water flow rate
- CONSUMPTION: Last-time water usage
- AVERAGE: Daily average usage over the past week (starting the next day)
- TOTAL: Cumulative water usage
RESTMO Brass Inlet Meter With Easy Install
This RESTMO model emphasizes durable brass construction and simple installation. The metal-threaded inlet/outlet resists corrosion and is compatible with standard hoses and fittings.

Buying Guide
- Durability and materials: Brass fittings resist corrosion and wear, extending meter life in outdoor environments. Choose units with brass inlet/outlet and metal threads for RV use and garden setups.
- Measurement modes: For RV filling and yard irrigation, four-mode meters (Flow, Consumption, Average, Total) provide real-time data plus historical usage. If you prefer simplicity, models like P3 P0550 offer clear accumulative readings.
- Readability: A clear LCD display and an adjustable (flip) screen aid readability from different angles, especially when installed on hoses or storage bays.
- Installation compatibility: Ensure the meter’s thread size matches common hoses and faucets. Bi-directional flow support can simplify mounting in tight spaces.
- Accuracy and calibration: Look for a meter with at least ±5% accuracy to reduce measurement error in lawn watering and RV filling scenarios.
- Maintenance: A rugged brass body is easier to clean and maintain than plastic variants. Consider models with removable components for easier cleaning of debris.
- Application flexibility: If you need RV filling alongside garden watering, select meters with universal hose compatibility and reliable readings under varying water pressures.
When comparing products, assess which features matter most for your use: real-time flow monitoring for immediate adjustments, or long-term usage data for scheduling efficient water use. A versatile meter with multiple modes supports both daily maintenance and long-term water management in RV parks, campsites, and home gardens.
