DIGITEN LCD Flow Controller With G1/2″ Sensor And Valve
Features a large LCD display that shows real-time flow rate, total volume, and temperature. It supports liters or gallons and allows LPM/GPM switching. The controller can automatically shut off the solenoid valve when the set flow value is reached, making it suitable for applications like preventing overflow in concrete mixers. It works with a variety of Hall effect flow sensors by adjusting the K value and includes a temperature sensor for liquid temperature measurement.
DIGITEN LCD Flow Controller With 1 Sensor And 3/4″ Valve
This version expands to a G3/4″ connection and supports flow rates up to 60 L/min. It features a large LCD screen showing real-time flow, totalized volume, and temperature. The unit provides quantitative control with automatic shutoff at a user-defined flow, and its compatibility with various Hall effect flow sensors is enhanced by adjustable K values. A temperature sensor helps monitor liquid temperature for precise process control.
DIGITEN LCD Display With 1/2″ Sensor And Valve
Designed for compact installations, this model combines a 1/2″ sensor with a 1/2″ solenoid valve and a 12V power supply. It provides real-time liquid volume per minute on the LCD and enables automatic shutoff when the preset flow value is reached. Sensor compatibility is maintained by adjusting the K value, enabling use with multiple sensor types and ensuring accurate measurements across different liquids.
DIGITEN LCD Flow Meter With Real-Time Flow Rate
This meter emphasizes quantitative control and real-time monitoring. It displays the real-time flow rate and can automatically shut the solenoid valve off when the target volume is reached. It is designed to work with all Hall effect flow sensors by adjusting the K value, providing versatility across different sensor types and installation scenarios.
DIGITEN 1” Flow Control With Sensor And Valve
Offers a larger 1″ connection, with a built-in controller that turns off the valve automatically when the desired flow value is reached. Like other models, it supports various flow sensors by adjusting the K value and displays the real-time liquid volume per minute. This option is well-suited for larger line sizes in industrial or agricultural settings where higher flow is common.
RESTMO Brass Inlet&Outlet Flow Meter For Outdoor Use
RESTMO adds a robust brass inlet and outlet with metal threading, designed for outdoor garden hoses, RV water tanks, lawn sprinklers, and nozzles. It features four measurement modes (Flow, Consumption, Average, Total) accessible via a single control push button. This model is ideal for hobbyist irrigation, leisure setups, and simple water monitoring without complex sensor integration.
Restmo Meter With Brass Inlet Outdoor Edition
This Restmo model continues the brass-inlet tradition with outdoor-ready fittings and four-mode operation: Flow, Consumption, Average, and Total. It is built for durability in outdoor environments and emphasizes straightforward, on-the-spot monitoring of water use in garden or RV settings. Its ergonomic design supports easy installation and readable LCD feedback for non-technical users.
Buying Guide: Key Purchase Considerations
When selecting a water flow control meter, consider the following factors to match your application and ensure reliable performance.
- Flow range and accuracy: Match the device’s maximum flow rate (L/min or GPM) to your system’s typical flow. Check the accuracy tolerance and readout resolution to ensure measurements meet your needs.
- Connection size and compatibility: Choose a model with compatible inlet/outlet threads (1/2″, 3/4″, 1″) to fit your piping. Ensure electrical and sensor interfaces align with existing equipment.
- Sensor compatibility: Many DIGITEN models support various Hall effect flow sensors. Confirm the required K value adjustments and whether your chosen sensor type is supported by the controller.
- Display and usability: A large LCD with clear units (L, gal, L/min, GPM) improves readability. Look for real-time rate, totalized volume, and temperature data if needed for process control.
- Automation features: Automatic shutoff at a set flow value is valuable for preventing overfill and protecting equipment. Check alarm options and ease of programming.
- Durability and environment: For outdoor use, brass fittings and weather-resistant housings extend lifespan. Indoor units should tolerate typical workshop conditions.
- Power and installation: Check voltage requirements (commonly 12V DC) and whether a power adapter is included. Assess ease of wiring and mounting options for your space.
- Maintenance and calibration: Ensure calibration procedures are documented and sensors are easily replaceable. Regular checks help maintain accuracy over time.
- Price-to-value balance: Consider whether you need basic flow monitoring or full automation with temperature sensing and alarm capabilities. Higher-end models offer broader sensor compatibility.
In summary, these meters provide flexible options for home irrigation, concrete mixing, or industrial water management. By aligning flow range, sensor compatibility, and automation features with your application, you can achieve precise control and reliable operation.
