Gamma ray density meter (non-contact density meter)
The density (concentration) of the fluid inside the pipe is measured from the outside of the pipe. No processing of the pipe is required.
Our gamma-ray density meter PM-1000Ex measures completely non-contact by simply being inserted into existing piping without any modifications. In contrast, conventional density (concentration) meters require the sensor to come into contact with the fluid, which can lead to sensor failure in acidic, alkaline, high-temperature, or high-pressure conditions. Additionally, in cases such as slurries, the sensor may become stuck, gradually causing measurement errors until it can no longer provide readings. The sensor of the PM-1000Ex does not come into contact with the fluid, and there is no pressure applied within the piping. Furthermore, by implementing appropriate insulation between the piping and the sensor, there is no influence from temperature. Therefore, it can measure fluids in acidic, alkaline, high-temperature, high-pressure, and slurry conditions without any issues. If you are experiencing troubles with other methods, please consider the PM-1000Ex. It uses weak gamma rays but is safe and not subject to regulations. 【Features】 - No need for the appointment of a supervisor or the establishment of controlled areas (certification for display-equipped certified devices has been obtained) - Lightweight and easy to install in existing piping - Can be installed in a small space *For more details, please download the PDF or feel free to contact us.
