With a minimum flow rate of 100mL per minute and a maximum working pressure of 10 psig, this compact and durable indicator is perfect for various tubing applications, ensuring efficient liquid management in any professional setting. ## Description The Bel-Art Scienceware 199350000 clear polycarbonate flow indicator provides immediate visual indication of the flow rate and direction of water and other liquids. The indicator has a nylon ball housed in clear polycarbonate housing that rotates in a circular channel during flow. An arrow indicates direction. Continuity and relative flow rate are indicated by the speed of the ball's rotation. The indicator requires a minimum water flow rate of 100mL per minute in a horizontal position and 140mL per minute in a vertical position and has an upper flow limit in excess of 1 liter/minute. The maximum working pressure is 10 psig (pounds per square inch gauge ) or 69 kN/m2 (kilonewtons per meter squared). The polycarbonate indicator is 30 x 57mm (11/5 x 2-1/4 inches) (H x W) and has two 23mm (0.9") tube extensions to accept 6.4mm (1/4") to 9.5mm (3/8") inside diameter (I.D.) tubing.

Obviously having air bubbles in a system is not ideal, but if it happens, good luck. There are a number of other edge cases which can cause issues, like the ball getting stuck over the outflow portion of the torus. Over all, this did not provide a quality solution, and I am still searching for an alternative. --- ## 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.ke/products/11137045-sp-bel-art-clear-polycarbonate-flow-indicator-3-x-2¼](https://www.desertcart.co.ke/products/11137045-sp-bel-art-clear-polycarbonate-flow-indicator-3-x-2¼) --- *Product available on Desertcart Kenya* *Store origin: KE* *Last updated: 2026-07-07*
