It features 1/4" OD connections, operates on 12 VDC power, and is calibrated for water, making it an essential tool for professionals seeking reliable liquid measurement solutions. ## Description McMillan S-Series Flow Meters are capable of measuring extremely low liquid flow rates from 13 mL/minute up to 5 L/minute with a full scale accuracy of ±1.0% or better! A wide variety of fluids may be measured. Repeatable results are achieved using a patented Pelton-type microturbine wheel. This proven design has been providing precision results since 1988 and has developed a well-deserved reputation for continuous operational service for many years without failure. Because of the compact size and economical cost of these products, the S Series flowmeters are suitable for a wide variety of industrial, commercial, laboratory and O.E.M. applications. Some sample applications include measurement of hydrocarbon fluids, fuels, light oils, solvents, coolant, pesticides, acids, alkalis, and deionized water. Plastic construction is suitable for use with many applications. A 3½ digit flow rate display is integrated into each unit and is programmed to read in milliliters per minute (liters per minute for 2 L/minute and 5 L/minute units). A cable assembly is included. 12VDC power is required. An optional 115VAC wall adapter is optional and available as a separate item. ## Features - 20-200 mL/minute (1/4" OD tube connections) - 12 VDC Power - 0-5 VDC Analog Output - ±1.0% Full Scale Accuracy (including linearity) - 0-50 degrees C operating temperature ## Images ![McMillan Flow S-111 Liquid Flow Meter, 20-200 mL/minute, 1/4" OD Connections, Integrated Display, Calibrated for Water - Image 1](https://m.media-amazon.com/images/I/81gaByBagPL.jpg) ![McMillan Flow S-111 Liquid Flow Meter, 20-200 mL/minute, 1/4" OD Connections, Integrated Display, Calibrated for Water - Image 2](https://m.media-amazon.com/images/I/61zGhC7dJfL.jpg) ![McMillan Flow S-111 Liquid Flow Meter, 20-200 mL/minute, 1/4" OD Connections, Integrated Display, Calibrated for Water - Image 3](https://m.media-amazon.com/images/I/61aURsdQqtL.jpg) ![McMillan Flow S-111 Liquid Flow Meter, 20-200 mL/minute, 1/4" OD Connections, Integrated Display, Calibrated for Water - Image 4](https://m.media-amazon.com/images/I/81o6zNVHKWL.jpg) ![McMillan Flow S-111 Liquid Flow Meter, 20-200 mL/minute, 1/4" OD Connections, Integrated Display, Calibrated for Water - Image 5](https://m.media-amazon.com/images/I/71BFF6aC4vL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/22866228-mcmillan-flow-s-111-liquid-flow-meter-20-200-ml](https://www.desertcart.co.uk/products/22866228-mcmillan-flow-s-111-liquid-flow-meter-20-200-ml) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
