Moisture meter for drywall and other sheet materials on conveyors

December 5 2022 г.

FIZEPR-SW100.15.1 is a moisture meter designed for non-contact measurements of moisture content in drywall, fiberboard, chipboard, medium density fiberboard plates and other sheet materials on a conveyor line. This moisture meter can also be used to measure moisture content in timber.

The moisture meter sensor has an operating temperature of +180ºС, so it can be used in drying chambers.

Measurement of moisture in crude oil with a high gas volume content

October 18 2020 г.

For all existing crude oil moisture meters, the metering error increases when gas appears in oil. For most of them, when gas volume content exceeds 2 - 5%, the metering error becomes unacceptable.

A solution has been found specifically for FIZEPR-SW100 series in-line moisture meters to ensure accurate crude oil moisture measurement even with a high gas volume content. The solution is shown in the figure.

CONCENTRATION ANALYZERS FIZEPR-SW100 OF ACIDS, ALKALIS AND SALTS

March 15 2019 г.

The new series analyzers designed for measuring concentrations of salt, acid and alkali solutions is put into production. Analyzers can also be used as moisture meters, but they can also measure materials with high electrical conductivity, such as anthracite, sewage sludge, ion-exchange resins (ion-exchange polymer), etc. Analyzers are used for in-line control of materials as well as for measurements in tanks and laboratory studies.

How does heterogeneity of the material affect the sensor reading if I make a measurement of moisture? How does material size modulus affect the sensor reading?

Due to the selected range volume of the material can be approximately represented as the sphere with a radius of about 25-30 cm. Therefore the heterogeneity within this volume is averaged. For accurate measurements size of material fractions should be approximately 10-20 times smaller than the wavelength. We use wavelength of about 1 m and if necessary it can be increased up to 7.5 m.
