DIGITEN Water Flow Control Meter LCD Display Controller G1/2
This DIGITEN model pairs a large LCD display with a flow-rate readout in real time, showing both instantaneous flow and cumulative total alongside sensed temperature. It supports liter or gallon units and a switchable LPM/GPM readout. The controller includes a quantitative control feature: it can automatically shut off the connected solenoid valve once the preset flow value is reached, making it suitable for concrete mixers and other timed filling tasks. It is designed to work with a variety of Hall-effect flow sensors by adjusting the K-value and includes a temperature sensor for broader liquid-temperature monitoring.
DIGITEN Water Flow Control Meter LCD Display Controller G3/4″
This larger-diameter variant extends the same valuable features to higher-flow applications. It provides a vivid LCD readout of real-time flow, total volume, and temperature, with LPM/GPM units available. The unit supports automated control of a solenoid valve to stop flow at a user-defined value and includes compatibility with various Hall-effect flow sensors through K-value adjustment. The model is designed for straightforward installation, helping protect batching or mixing operations from oversupply and enabling reliable automated shutoffs.
DIGITEN Water Flow Control LCD Display+1/2″ Flow Sensor Meter
This compact DIGITEN kit combines a 1/2″ flow sensor with a robust LCD display and a controlled solenoid valve. It delivers real-time flow readings and supports adjustable K-values to accommodate various sensor types. The system is designed to automatically cut flow when the target volume or rate is reached, enabling precise control for small mixing tasks, irrigation lines, or household water management projects. The included controller supports dynamic readings of volume per minute and totalized amounts for traceable usage data.
DIGITEN Water Flow Control LCD Display Meter Quantitative Controller
This model emphasizes quantitative control and real-time monitoring with a focus on automatic shutoff when the target flow is achieved. It supports a variety of Hall-effect flow sensors with adjustable K-values to match sensor displacement, making it adaptable for different liquids and tubing setups. The display shows real-time flow and total volume, enabling ongoing verification of performance and efficient system management, useful for batch dispensing and water-tight applications across residential and light commercial settings.
RESTMO Water Flow Meter With Brass Inlet
RESTMO’s model features a heavy-duty brass inlet with metal threading for durable outdoor use. It provides four modes to display data: Flow (real-time rate), Consumption (last usage), Average (daily average by week), and Total (cumulative usage). The durable construction makes it well-suited for garden hoses, RV water filling, lawn sprinklers, and other outdoor water tasks. The device includes a clear LCD screen and a simple one-button control to switch modes, enabling straightforward monitoring of water usage and flow across different scenarios.
NJBVRS Water Flow Sensor Digital LCD Display
This sensor-focused option offers a compact 3/8″ inlet housing with a 1/4″ flow path option and a broad measurement range up to 999,999 liters. It emphasizes compatibility with various fittings and simple integration into small-scale systems. While primarily a sensor, it pairs with display and control components to monitor flow in real-time and log total usage, suitable for hobbyist projects, DIY irrigation lines, and compact fluid-control tasks where space is limited.
Buying Guide: Key Purchase Considerations
- Flow range and sensor compatibility: Choose a model whose measurement range matches your application (e.g., 1-30 L/min vs. 1-60 L/min). Ensure the device is compatible with your existing flow sensors or compatible Hall-effect sensors, and verify adjustable K-values for sensor calibration.
- Display and data: Prefer units in liters or gallons with real-time flow, total volume, and temperature where available. A clear LCD, easy-to-read units, and reliable data logging improve usability for monitoring and control.
- Automation and control: If your goal is automatic shutoff, select models with programmable setpoints and a dependable solenoid valve. Consider ease of installation and whether the controller supports easy integration into your current plumbing or pump setup.
- Durability and installation: Brass inlets and metal threads offer robust outdoor performance. Look for weather resistance and seals suitable for the environment (indoor workshop vs. outdoor garden hose).
- Power and wiring: Check power requirements (DC 12V in these models) and cable management options to avoid interference or tripping hazards in crowded installations.
- Maintenance and compatibility: Ensure compatibility with your existing components and consider maintenance needs, such as sensor calibration intervals and the availability of replacement parts or sensors.
- Application scope: Determine whether you need a compact sensor-only option or a full LCD display with control features for automated shutoffs in batching, irrigation, or concrete mixing contexts.
