Product comparisons
Side-by-side comparisons of Pisonics density and concentration meters versus international brands. Facts only, full feature matrix — draw your own conclusions.
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.
A non-nuclear alternative to Berthold's radiometric (Cs-137) density gauge. The Pisonics PS7000 measures slurry and FGD density by ultrasonic acoustic impedance — no radioactive source, no radiation licensing, no source disposal — while matching the accuracy a minerals plant needs. Compared on principle, accuracy, regulatory burden, installation and lifecycle cost.
Side-by-side specifications for two ultrasonic density meters deployed in slurry applications — covers principle, range, installation, and local service.
PS7000 and Rhosonics SDM ECO are both non-nuclear ultrasonic acoustic-impedance density meters. This table compares specs, installation, price, and service network.
The Pisonics PS7000 (ultrasonic acoustic-impedance, sapphire window in direct contact with the slurry) and a clamp-on ultrasonic density meter (transducers strapped on the pipe exterior, through-transmission) both measure slurry, FGD-slurry and tailings density / concentration online. Three differences matter most: (1) lined pipe — the clamp-on must transmit through the pipe wall and liner, and strongly absorbing liners (rubber, ceramic, thick PTFE) often cannot be measured, whereas the PS7000 window sits inside the pipe and the measurement bypasses the liner; (2) bubbly slurry — the clamp-on long transmission path is disturbed by bubble scattering and tends to drift or lose lock, while the PS7000 uses a short reflection plus Chirp bubble rejection and stays stable; (3) couplant — the clamp-on needs acoustic couplant that dries / migrates over time, temperature and vibration and must be re-applied periodically, while the PS7000 couples through the slurry itself and needs none. The PS7000 is also independent of the pipe wall, needs no full pipe, holds ±1% FS and is maintenance-free for 5+ years; the clamp-on advantage is being non-invasive and movable without shutdown.
The Pisonics PS7000 (non-nuclear ultrasonic acoustic-impedance) and the Russian Ecophyspribor IPB-1K (Na-22 gamma source) both measure slurry, mud and FGD-slurry density/concentration online. Three differences matter most: accuracy — the PS7000 holds ±0.005 g/cm³ absolute, roughly 5× tighter than the IPB-1K (±1% of full scale ≈ ±0.027 g/cm³); lifecycle cost — Na-22 has a half-life of about 2.6 years, so the source typically needs replacing roughly every 2 years (each replacement means source purchase, transport, installation/recalibration and spent-source return), whereas the PS7000 has no source and no such recurring cost; and the compliance threshold — holding more than 10 source-bearing meters at one plant requires a Radiation Safety License.
