I only need transmitters.** A: No, the receivers are marked with R and transmitters with T. You could experiment and see. If you don't want to experiment, assume they are not the same and you must use R for receiver and T for a transmitter. **Q: Do these do their own tone generation/demodulation? Or are they effectively high-frequency speakers/mics and an external circuit does the processing?** A: They are effectively a high frequency speaker/mic **Q: Can you use this to measure flow rate in a pressurized water pipe? How about gas?** A: Most likely for water. For gas, it would depend on the gas density, and the sensitivity of your circuit. I was able to get some pretty precise nodes in my setup for other things, so provided you know the math needed to calibrate the system, it should get job done. Are you trying to measure the speed using flight time or doppler? **Q: How weatherproof are they?** A: These ones are not waterproof. ## Frequently Bought Together - HiLetgo 20pcs TCT40-16R/T 16mm Split Ultrasonic Sensor Ultrasonic Transceiver Probe 10 Transmitters + 10 Receivers T+R Ultrasonic Sensor Set - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - HiLetgo 4pcs Ultrasonic Sensor Integrated Transceiver Waterproof Diameter 16MM --- ## 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.com.kw/products/726095941-hiletgo-tct40-16r-t-16mm-split-ultrasonic-sensor-ultrasonic-transceiver](https://www.desertcart.com.kw/products/726095941-hiletgo-tct40-16r-t-16mm-split-ultrasonic-sensor-ultrasonic-transceiver) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-16*
