Flow Monitoring in Explosive Atmosphere

Based upon a proprietary oval gear design, Titan's OG Series flow meters are designed to give reliable, high performance across a wide range of applications. Unlike other types of flowmeter, the measurement accuracy of these oval gear flow meters improves as liquid viscosity increases, from a nominal 1% towards 0.1% of flow rate at higher viscosities. OG flowmeters are also available to pressure in excess of 700bar, where required. Standard versions of these Oval Gear flow meters use electrical pulsed outputs and therefore Titan has developed options to ensure they meet the requirements for safe use in hazardous atmospheres

Two options for ATEX compliant operation 

A simple option for monitoring flow in an explosive atmosphere is based upon using a Reed switch that operates via the customers intrinsically safe circuit. Employing this design there is no potential for storage or generation of electricity, allowing the Oval Gear flow meters to fall under the “Simple Apparatus” definition. These units can therefore be used without the need for ATEX certification.

The second ATEX compliant approach uses a fully certified NAMUR Proximity Switch to give the pulsed output from the oval gear meter. For customers that elect for this option, Titan will install the switch into the Oval Gear flow meter and can supply the appropriate amplifier if required The OG meters are offered with Stainless Steel, Aluminium, PEEK and Hastelloy housing options to provide a comprehensive range of chemical compatibility to suit almost any application.
