Overview

Food, brewing and sugar industries widely need concentration measurement: Brix, alcohol, wort, juice concentration, dairy total solids. Compared with heavy industry these sectors prioritize non-intrusive measurement, hygienic design and zero radioactive sources (to avoid both licensing and public concern).

PS7020

Inline Ultrasonic Concentration Meter

The PS7020 series inline ultrasonic concentration meter determines concentration from a quantity that can be measured directly: the time an ultrasonic pulse takes to cross the medium. The acoustic path length is fixed by the measuring spool, so the transit time gives the sonic velocity, which is converted to concentration or density through a calibration table established on the actual liquid. The instrument is of integral construction, with no moving parts, no consumables and no radiation source.
PS7021

Inline Ultrasonic Phase Separation Detector

PS7021 decides the phase from sound velocity: time of flight over a fixed path gives the velocity, the amplitude of the same echo gives the scattering, and together they separate heavy phase, rag layer and light phase. Three volt-free relays drive the diverter valve directly. On a pair like dichloromethane and water — a third apart in density yet nearly identical in acoustic impedance — density and impedance instruments cannot tell the phases apart, while the velocities differ by 390 m/s. DN25 / DN32 / DN50 spools, 316L with sapphire windows or PTFE-lined.
PS7400

Online tuning fork density meter

The PS7400 series online tuning fork density meter monitors liquid density in real time by leveraging piezoelectric excitation and changes in the tuning fork’s resonant frequency, requiring no maintenance while delivering highly accurate, repeatable measurements. Its built-in PT1000 temperature compensation eliminates drift due to temperature variations, making it suitable for diverse industrial applications such as pipelines and storage tanks, and widely used in the petrochemical, chemical, and pharmaceutical industries.
PS7200

Coriolis density meter

The PS7210 density meter employs the Coriolis force principle and achieves high‑precision, long‑term stability with no sensor drift through pure‑physical frequency measurement. It is suitable for continuous online monitoring of a wide range of liquids, including those in the petrochemical, brewing, and chemical industries—covering acids and alkalis—and supports installation in bypass lines or buffer tanks.
PS7110

Refractive concentration meter

The PS7110 series measures the refractive index of the medium by critical-angle refractometry and converts it to concentration through a scale. The measurement takes place in a thin layer at the prism face, so colour, turbidity and bubbles do not interfere; a built-in temperature sensor feeds the compensation, and index and temperature are calibrated in standard units unit by unit at the factory. Three variants, A / B / C, differ in prism material and process temperature.
PS7100

Spectroscopic concentration meter

The PS7100 series spectral concentration/density meter employs multi-channel full-spectrum technology to deliver real-time, reagent-free, and undiluted high-precision concentration measurements. Based on the Lambert–Beer law, this instrument provides broad coverage across the ultraviolet, visible, and near-infrared spectra, making it suitable for industries such as chemicals, pharmaceuticals, and food & beverage, and particularly well‑suited for concentration monitoring in complex multiphase systems.
PS7300

Pipeline Differential Pressure Density Meter

Online differential pressure density meter uses a special density sensor to measure the density of various liquids or liquid mixtures online, directly reads the density value and outputs a 4-20mA DC signal with HART communication protocol. It is widely

PS7020 Series Ultrasonic Sound Velocity–Based Concentration/Mass Density Meter: Applications in the Food, Brewing, and Sugar-Refining Industries

In the wort mashing, filtration, and fermentation stages of beer brewing, customers face challenges such as delayed wort concentration measurements, bubble interference, and poor performance with dark-colored liquids, resulting in significant batch-to-batch variability and frequent manual sampling. The PS7020 series ultrasonic sound-velocity–based concentration/density meter measures wort °P online with an accuracy of ±0.0005 g/cm³, unaffected by color, bubbles, or CO₂. Equipped with a hygienic clamp‑type quick‑connect and compatible with CIP/SIP, it delivers sub‑second real‑time feedback and seamless integration with MES systems.

Inline Brix monitoring in sugar refining and brewing

Inline refractometric measurement of sugar liquor, glucose and brewing process concentration: critical-angle refractometry reads only a thin layer at the prism face, so colour and turbidity do not interfere. Scales are built per medium, with CIP / SIP and a sanitary adapter.

Edible oil refining — oil / wash-water phase detection after neutralisation

Oil-water discrimination on the 80-90 °C wash stage after alkali neutralisation. Temperature is the lever: the phases are 66 m/s apart at ambient and 287 m/s apart at 85 °C, because oil's coefficient is negative and water's is positive. Hot is both the natural state of this duty and the state with the most margin. The page also covers how fouling shows in the amplitude baseline first, and why a sanitary execution has to be confirmed separately.

Industry FAQ

What sanitary requirements does food/brewing have, and can Pisonics meet them?

Hygienic requirements for food and beverage production:

  1. Wetted materials — 316L stainless steel, polished (Ra ≤ 0.4 μm), PTFE, sapphire;
  2. Process connections — sanitary clamp (Tri-Clamp), ISO food-grade flanges;
  3. CIP/SIP cleaning — resistant to 90°C hot water, chemical cleaning with 3% NaOH/3% HNO3, steam sterilization at 134°C;
  4. Dead‑free design;
  5. Compliance certificates — FDA 21 CFR, EHEDG, and 3-A certification (for select models).

Pisonics hygienic‑grade versions: PS7400 tuning fork (clamp connection + 316L polishing + PTFE coating), PS7110 refractometer (sapphire prism on the B and C variants, optical glass on the A; tri-clamp or the PS7110-MT4 sanitary adapter, CIP and SIP capable), PS7020 sound velocity method (PTFE wetted parts), PS7210 Coriolis mass flow meter (sanitary clamp).
