The parameters are not difficult to input, but we could not get it to give us a consistent reading. We are trying to use it on a long length of 3" stainless pipe. Still gave it 3 stars, because possibly I am missing something that will make it work. I will update the review if we get it to work correctly. ### ⭐ It is not a new unit. Used and full of scratches! *by A***R on October 20, 2018* I resell flow meters, I decided to try from this seller 2 sets of TUF-2000M because it was on promotion but I had to return it and I can not give this to my customers! Full of scratches, no manual and Chinese letters! --- ## 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.tn/products/69893942-tuf-2000m-tm-1-ultrasonic-flow-meter-flowmeter-dn50-700mm](https://www.desertcart.tn/products/69893942-tuf-2000m-tm-1-ultrasonic-flow-meter-flowmeter-dn50-700mm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
