Pisonics vs Rhosonics — Non-Nuclear Ultrasonic Density Meters Compared
Looking for a Rhosonics density meter alternative? Both Pisonics and Rhosonics build non-nuclear ultrasonic slurry density meters on the acoustic-impedance principle. This page compares the two brands on principle, accuracy, lead time, service network, customization and total cost — and links to model-by-model breakdowns.
Feature comparison
| Feature | Slurry density meter | Rhosonics Slurry Density Meter (SDM) range |
|---|---|---|
| Measurement principle | Non-nuclear ultrasonic — Chirp wideband acoustic impedance (linear FM) | Non-nuclear ultrasonic — acoustic impedance |
| Product line | PS7000 / PS7010 / PS7020 — impedance · attenuation · sound-velocity | SDM / SDM ECO slurry density meter range |
| HQ & manufacturing | Xi'an, China — factory-direct | Putten, Netherlands — overseas HQ + regional agents |
| Density accuracy | ±0.005 g/cm³ | ±0.005 SG (per Rhosonics datasheet) |
| Repeatability | ±0.0005 g/cm³ | — (verify on rhosonics.com) |
| Wetted materials | 316L / 2205 / Hastelloy / Ti / Ceramic / PTFE | Ceramic + Duplex 2205 + 316L |
| Lead time | 2–4 weeks std / 6–10 weeks custom | 8–12 weeks typical (import) |
| Service response | China factory engineers + multilingual overseas team | Overseas HQ + China/regional agents |
| Customization (materials / range / Ex / sanitary) | Deep, factory-level | Standardized product |
| Total cost (same configuration) | Substantially lower | Premium import pricing |

Takeaway
Rhosonics is a well-established international brand with broad global project experience, and its SDM line is a proven non-nuclear ultrasonic density meter. Pisonics builds same-principle meters in China with three advantages that matter most for overseas and response-sensitive projects: shorter lead time (2–4 weeks vs 8–12), factory-direct service and total cost, and deeper customization of materials, range and hazardous-area certification.
