Titan Enterprises offer specific design options for challenging applications. In this article we examine ATEX compliant flow meters. Titan design robust oval-gear flow meters to ensure safe operation in potentially explosive atmospheres – such as those often encountered within the petrochemical industry.
Based upon a proprietary oval gear design, Titan OG Series flow meters are manufactured to deliver reliable, high performance flow measurement across a wide range of applications. Unlike other types of flow meter, the measurement accuracy of Titan oval gear flow meters improves as liquid viscosity increases, from a nominal 1% towards 0.1% of flow rate at higher viscosities. Titan ATEX compliant flow meters are also available to pressures in excess of 700bar – where specifications dictate high pressures. 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 variants of ATEX compliant flow meters
A simple option for ATEX flow meters and monitoring flow in an explosive atmosphere is based upon using a reed switch operating via the customer’s intrinsically safe circuit. By employing this design there is no potential for storage or generation of electricity, allowing the Titan oval gear flow meters to safely pass “Simple Apparatus” safety requirements. These units can therefore be used without the need for ATEX compliant flow meters certification.
The second ATEX flow meter compliancy 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 imanufacture the switch integral with the flow meter and can supply the appropriate amplifier – if required.
For any installation of ATEX compliant flow meters into potentially explosive atmospheres, operators must ensure that correct standards are maintained for the full electrical installation. With the two options available throughout the Titan OG range, Titan customers have the facility to optimise their installation to process and environmental requirements.
The Titan OG range is offered with Stainless Steel, Aluminium, PEEK and Hastelloy housing options to provide a comprehensive range of chemical compatibility to suit almost any application.
