PS7000 Acoustic Impedance vs PS7010 Acoustic Attenuation: Ultrasonic Density Meter Comparison

Both PS7000 and PS7010 are ultrasonic density meters, but their physics, installation, and target applications differ completely. This 6-dimension comparison helps you choose between them.

Customers often ask why we offer two ultrasonic density meters. The answer: different physics. Acoustic impedance measures interface reflection; acoustic attenuation measures transmission absorption. Each is strong in its own niche. This article compares them across 6 key dimensions.

Steps

  1. Measurement principle

    PS7000 acoustic impedance (single transceiver, spectral echo analysis) vs PS7010 acoustic attenuation (dual probes opposite, energy absorption measurement).
  2. Installation

    PS7000 flange insertion (tap required); PS7010 clamp-on (preferred) or flange, can install without tapping.
  3. Bubble tolerance

    PS7000 Chirp algorithm strongly bubble-immune; PS7010 single-frequency is bubble-sensitive. Choose PS7000 for gassy media.
  4. Pipe wall requirements

    PS7000 doesn't depend on wall properties; PS7010 clamp-on requires uniform wall material and stable thickness (carbon steel / stainless OK, plastic / rubber-lined not).
  5. Pipe size range

    PS7000 DN50~DN1000; PS7010 DN50~DN500 (clamp-on mode).
  6. Typical applications

    PS7000: flotation slurry, FGD gypsum slurry, mining slurry, dredging discharge. PS7010: hot-work-forbidden petrochemical zones, legacy pipe retrofits, temporary monitoring.
