Titan Enterprises provides new special options for its Oval Gear flow meters to enable safe operation in potentially explosive atmospheres such as in the petrochemical industry.

Based upon a proprietary oval gear design, Titan OG Series flow meters are manufactured to give reliable, high performance among a broad range of applications. 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 of more than 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.   

Titan offer two options for ATEX compliant operation of its Oval Gear flow meters in explosive atmospheres

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  

For any installation in potentially explosive atmospheres, operators must ensure that correct standards are maintained for the full electrical installation, but with the two options available throughout the Titan OG range, you have the choice to optimize your installation depending on process and environment requirements. 

The OG range is offered with Stainless Steel, Aluminum, PEEK and Hastelloy housing options to provide a comprehensive range of chemical compatibility to suit almost any application.
