DIGITEN Liquid Flow Controller With LCD Display
The DIGITEN device combines a liquid flow sensor with a G1 connection and an LCD display to show quantitative flow readings. It supports connections to temperature sensors and solenoid valves for automated control. The system can monitor gases or liquids and provides a total flow alarm, with the flow sensor compatible with Android and Raspberry Pi environments. Setup is designed for straightforward installation and configurable flow control. When the preset flow is reached, the device outputs a signal to the solenoid valve to switch ON or OFF.
GREDIA Digital LCD Flow Controller For Liquid
The GREDIA unit emphasizes real-time monitoring of flow rate and total flow, with the ability to drive a solenoid valve for automated control. It can display liquid temperature when paired with a temperature sensor. Users should plan for the temperature sensor as an optional add-on, enabling integrated temperature-aware flow management in systems where temperature affects viscosity or density.
Yuly 1.25″ Stainless Steel Flow Sensor Controller
The Yuly liquid flow sensor combines a stainless steel body with a flow rotor assembly and a sensor. The wiring uses a simple color-coded scheme (Red for positive, Yellow for signal, Black for ground). Its all-stainless construction offers robust sealing and straightforward installation, making it suitable for clean water lines and chemical compatibility contexts where corrosion resistance matters.
QLWAHK 1/4″ Brass Mass Flow Controller
This compact brass flow controller uses a Hall-effect sensor design to measure and regulate flow. It is suitable for applications where a small footprint is essential and where brass is compatible with the fluid. It supports standard flow sensing in a compact package, making it a good choice for integrating into tight assemblies or pilot systems.
VWKYFRF Mass Flow Controller Series
The VWKYFRF option mirrors the Quest for compact brass flow controllers with Hall sensors. It provides flow sensing in a small format suitable for integration into compact hardware setups and lab rigs. A focus on flow sensing compatibility makes it a suitable pick for systems that require precise control in tight spaces.
MBVAIDQ Compact Brass Flow Controller
The MBVAIDQ unit emphasizes compact brass construction with a focus on small 0.35-3.0 L/min flow ranges. It is designed for applications where moderate flow control is needed in a small housing, balancing size and performance for light industrial or lab tasks requiring reliable flow regulation.
VCIMZUL Compact Flow Controller
The VCIMZUL option provides another compact brass mass flow control solution with a 0.35-3.0 L/min range. Ideal for tight assemblies, it supports similar sensing techniques and is suitable for integrating into systems where space is at a premium and precise control is required.
TC5218 High-Precision Mini Mass Flow Meter
The CJLHENZM TC5218 unit is a high-precision mini mass flow meter designed for both air and liquid measurements, featuring a 4-20 mA output suitable for integration with industrial controllers. Its precision and electrical interface support make it adaptable for use in automated systems requiring accurate flow readouts and control signals.
Buying Guide: Key Purchase Considerations
- Fluid compatibility: Check material compatibility (brass, stainless steel, plastics) with the liquid or gas being measured. Corrosion resistance and cleanability matter in sensitive applications.
- Flow range and resolution: Match the device range (e.g., 0.35-3.0 L/min) to the expected maximum and minimum flow. Higher resolution improves control in tight tolerances.
- Sensor type and output: Hall-effect sensors are common for compact controllers; 4-20 mA outputs suit many industrial controllers. Ensure digital interfaces (Android, PI, etc.) align with your system.
- Temperature considerations: Some units support temperature display or require an external sensor. Temperature affects liquid density and viscosity, influencing flow accuracy.
- Valve integration: If you need automatic shutoff or regulation, verify compatibility with solenoid valves and the control logic (ON/OFF or continuous modulation).
- Installation footprint: For tight spaces, consider compact brass or stainless-steel housings. Mounting options and seal integrity impact reliability.
- Maintenance and calibration: Assess ease of calibration and cleaning, especially in processes with particulates or viscous fluids.
- Electrical requirements: Review supply voltage, wiring color codes, and mounting orientation to ensure safe integration with existing control systems.
- Certifications and standards: Depending on the application, confirm compliance with industry standards and safety regulations.
When selecting a liquid mass flow controller, identify whether you need simple monitoring with occasional control, or integrated automation with real-time feedback and alarm signaling. The five options above offer a spectrum from direct LCD-display controllers to compact, sensor-first devices, enabling you to tailor a solution to your system’s size, fluid, and precision needs.
