The new Triangle system, using innovative field time control technology, is specifically designed to give high accuracy flow rate measurement of bulk solids such as powders and granulates.
The Triangle system is specifically designed for measuring the flow rate of powders, granulates and other bulk materials even in difficult applications such as pneumatic conveying or ‘free fall’. This new flow rate system consists of a sensor with transmitting and receiving electrodes and an indicating transmitter/totaliser. It employs innovative ‘Field Time Control’ technology where a concentrated electric field is generated between the sensor’s transmitting and the receiving electrodes. The reaction time of the sensor increases as soon as the solid particles interfere with the electric field and the sensor signal output corresponds to the flow rate of the bulk material.
Field Time Control technology incorporates several features designed to obtain optimum results for pneumatically conveyed materials with variable product/air ratio or products in free fall after mechanical conveying. In particular, its ability to detect weak signals coming from low dielectric products allows high accuracy measurement in such applications compared to other flow rate instrumentation.
The Triangle system has a reliable and robust design for industrial applications and harsh environments. The rigid stainless steel sensor includes a ceramic isolator for abrasive materials; typical applications include measurement of polymer powders in the waste water industry and super absorbent pellets in the nappy industry. The ATEX approved transmitter includes multiple display functions (instantaneous flow rate, total, accumulated total, analogue output and frequency counts) and is offered with various types of enclosure including a rugged aluminium field mount enclosure with IP67 rating. Overall, the Triangle system is easy to install, has no moving parts and requires minimal maintenance, providing a reliable and cost effective solution for solid flow applications.
The Triangle flow rate system is developed by Fluidwell Instruments and is available through icenta Controls, the UK specialist in flow solutions, instrumentation and control. Whatever the application, icenta can offer the right solution from a range of flow technologies and flow meter options.
