If you need it, you can search for "3.6V 2000mAh Ni-MH Battery" to buy. As for calibration, the machine is already calibrated at the factory and does not need to be calibrated. **Q: will it give instant readings GPM on the handheld or do i need softwear?** A: Hello, the handheld flowmeter will display the real-time reading of GPM, but if you need the measurement data in the past period of time, you need to use the software. ## Frequently Bought Together - Bonvoisin Handheld Ultrasonic Flow Meter Portable Clamp on Flowmeter with Data Output S1+M2 Sensors for Seawater Alcohol Industrial Sewage DN15-700mm (1/2-28") - Aquasonic Aquasonic 100 Ultrasonic Gel, 250ml (8.5 Oz) Dispenser - Each, 8.45 Fl O --- ## 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.gr/products/735600691-bonvoisin-portable-ultrasonic-flow-meter-clamp-with-data-output-s1](https://www.desertcart.gr/products/735600691-bonvoisin-portable-ultrasonic-flow-meter-clamp-with-data-output-s1) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-04*
