RHOSONICS COMPANY BROCHURE

CONTINUOUS IN-LINE MONITORING & PROCESS CONTROL

RHOSONICS – 25 YEARS

In April 1992 Rhosonics was founded by Mr.

Willem van Ballegoijen de Jong. Today, the

company is led by his son, Mr. Guus van

Ballegoijen de Jong. The employees at

Rhosonics proudly celebrated the company’s

25th anniversary at the newly opened premises

in Putten, the Netherlands in April 2017.

ISO9001 CERTIFICATION

After being initially certified in 2010 for ISO

9001:2008, the company processes were

audited and were found to also be in

compliance with ISO 9001:2015.

OUR CORE VALUES

We provide instruments for customers who

want to monitor their process and reach the

desired product quality and productivity.

Our team of experts is continuously looking

for improvements of existing products

through innovative measurement solutions.

We use craftmanship, capability and creativity

to create measurements beyond limits.

MEASURING BEYOND LIMITS

Our promise to our customers. Customers

will achieve the best measuring results when

using Rhosonics instruments. Beyond limits

stands for our ambition to create process

instrumentation with leading product

quality, robust designs, the most reliable

technology, the best measuring results and

beyond.

At Rhosonics, we believe that we can offer a

measurement solution for virtually all

process liquids in any industry.

TECHNOLOGY

All instruments of Rhosonics use ultrasonic

measuring technologies. Ultrasonic pulses

(approx.: 2.3 MHz) are created by a piezo

element located in the sensor tip. The piezo

element sends the ultrasonic pulses into the

medium and also receives all returning

signals. Then the signals are transferred to a

transmitter for further processing and

calculation of the measuring results.

The three ultrasonic parameters which are

measured are sound velocity, attenuation

and acoustic impedance.

All these parameters are influenced by

temperature. Therefore the temperature is

also measured in most of the applications,

for example by a Pt100 temperature probe.

The physical parameters are translated into

the measurement value by making use of

polynomials. These polynomials are unique

for every application and created by

Rhosonics. The final choice for one or

multiple physical parameters depends on

the specific application, fluid properties and

installation requirements.

DIFFERENT MEASUREMENTS

Acoustic impedance

The acoustic impedance is the reflection

of energy at the interface between the

sensor and the slurry or liquid. This is

used for density measurement and for

certain concentration applications.

Sound velocity

The sound velocity or speed of sound is

determined by measuring the time that

the ultrasonic signal is traveling over a

known distance. This distance can be

between the sensor tip and a reflector

plate or over the pipe diameter. The

sound velocity is used for the

measurement of a concentration.

Attenuation

Solids absorb ultrasonic energy. We

measure the loss of energy over a

particular distance, such as a pipe

diameter. Those losses are a value for

the amount of solids, expressed in wt%

or g/liter.

Combined sensor technology

The ultrasonic parameters mentioned

above are sometimes combined with a

conductivity measurement to measure

two components of a ternary liquid.

Our Technology

DENSITY METERS

Rhosonics Density Meters are used in the

mining, dredging, construction and energy

industries to measure the density of a

mineral slurry. Our newest product is the

Slurry Density Meter (SDM).

SOLIDS METERS

The Solids Meters can be used for many

industry applications, such as measurement

of solids in the food industry and measuring

solids in mineral slurries. The Model 9670

can be used for mineral applications.

PLATO / BRIX METERS

Plato Meters are used for product control in

various stages of the brewing process. The

Plato Meter F43 is the newest model. Brix

meters are used to measure the sugar

content of a process liquid in °Brix.

CONCENTRATION METERS

Concentration meters are used to accurately

measure one component of a chemical

solution, for example the concentration of

NaOH or H2SO4. Our model 8500 is usually

used for these kind of applications.

METERS FOR TERNARY LIQUIDS

Concentration Meters for ternary liquids can

measure two components of a (chemical)

liquid solution. The B31 is the newest model

and can for example be used for TMAH+PR

measurement in the flat panel industry.

COD METERS

COD Meters are used in the influent flow of

industrial wastewater treatment plants. The

model 9585 measures the COD value and

helps to protect against high COD peak loads

and allows further optimization of the WWTP.
