Product Description
1.NOTE
The MH-01 (2-in-1) model includes flow and TDS monitoring by default. It supports optional micro (1mm, 0.1–1L/min) or large bore (4mm, 0.3–3L/min) sizes, and can be configured with either integrated or split cable designs.
MH-01 (3-in-1) and MH-02 (3-in-1) models come with flow, TDS, and temperature sensing functions, using an integrated 6-wire cable only.
All models operate on DC 5–18V and offer ±3% flow detection accuracy. The standard MH-01 (2-in-1) does not include temperature sensing, but customization is available.
Some configurations may not be shown due to listing limitations. Please leave a note at checkout or contact us if you have specific requirements.

3. Features
2-in-1 or 3-in-1 Functionality
Choose between basic (flow + TDS) or enhanced (flow + TDS + temperature) models for flexible use cases.
Customizable Design (2-in-1 Only)
Optional micro bore (1mm, 0.1–1L/min) or large bore (4mm, 0.3–3L/min), and integrated or split cable design — only available for the 2-in-1 version.
6-Wire Integrated Version for Full Monitoring
The 3-in-1 version comes with an integrated 6-wire structure, ideal for compact systems with full data feedback.
Precise & Stable Signal Output
±3% flow accuracy, clean pulse signal, and ultra-fast response for accurate real-time monitoring.
Optional Temperature Sensing (2-in-1 Custom)
The standard 2-in-1 model does not support temperature sensing, but customization is available on request.
4. Application
Smart RO Water Filtration Systems
Water Quality Monitoring in IoT Devices
Home & Industrial Water Purifiers
Lab-Grade Low-Flow Fluid Measurement
Precision Water Control in Smart Appliances
5. FAQs
Q1: Do all MH-01 sensors support temperature monitoring?
A1: No. Only the 3-in-1 version (with 6-wire integrated cable) supports temperature sensing. The standard 2-in-1 model supports flow and TDS only.
Q2: Which models offer split cable installation?
A2: Only the 2-in-1 version of MH-01 supports both integrated and split cable designs. The 3-in-1 versions (MH-01 & MH-02) come only with integrated cables.
