The frequent and important peculiarity which should be considered in any kind of industry and production is that the material used in the production process has got a certain amount of moisture in it.
It goes not only about bulk materials (such as sand, rubble, ore, gravel etc), but about liquids as well (oil, fuel oil, coal-water slurry fuel (CWSF), petroleum etc).
Though all the versions of the moisture meter have got similar structure each versions performs its own function.
The device consists of an electronic unit and a sensor.
The flanges of the sensor which is made as a pipe section are made of stainless steel. A probe which is inside the pipe is made as a flat-topped stick of stainless steel of the same grade.
Because of the probe being equipped with a thermocouple, it is possible to carry out temperature control. The length of the pipe section with the flanges is 400 mm.
The moisture meter is available in several versions with different nominal bore: DN 50, DN 80 and DN 125 mm, and different allowable pressure: PN 1.6 (16 atm); РN 2.5 (25 atm); РN 4.0 (40 atm); РN 6.3 (63 atm) and РN 10.0 (100 atm).
All the parameters can be adjusted depending on the needs of the customer. Due to the material the moisture meter is made of the device is resistant to corrosion, abrasive materials, mechanical stress. 
The electronic unit can have an explosion-proof enclosure as well as the general purpose version.
Moisture meters for liquid materials are used in boiler installations, water-dosing and diesel oil emulsion dispersion systems.
The scope of supply can include the control cabinet to operate the valves regulating water feed. The moisture meter for liquid materials has a processing unit with RS232/RS485 interfaces (can be easily included into ACS-automatic control systems);
and its supply package includes software suitable for Windows, as well as the control cabinet to operate the valves regulating water feed.
