Sensor of the Month – The Polyurethane (PU) Densitometer

This month we’re excited to showcase the Polyurethane (PU) Densitometer Sensor.

This Densitometer uses ERT tomography to give a concentration measurement based on the volume of solids flowing through a pipe. It can replace nuclear-based gamma densitometers, therefore does not require a nuclear source, which have obvious health and safety concerns and come with complex regulatory and licensing controls.

Commonly used in dredging and mining applications, the Densitometer has proven to be very effective at providing density measurements in real-time as well as additional rich datasets derived from the tomogram or cross-sectional conductivity image of the pipe

The sensor pictured is 500mm inner diameter, but the largest size produced to date has been 1,300mm inner diameter. The PU liner is cost-effective and provides strong resistance to wear & abrasion and is durable in harsh environments.

ERT | Electrical Resistance Tomography

The basic principles of electrical resistance tomography (ERT) are to take multiple measurements at the periphery of a process vessel or pipeline and combine these to provide information on the electrical properties of the process volume.

Why Do Customers Like The Densitometer System

The Polyurethane (PU) Densitometer Sensor system allows customers to monitor their production in real-time, enabling them to reduce process downtime and increase efficiencies.
