The Contrec 202A Loop-Powered Flow Rate Totalizer is specifically designed to work seamlessly with any flowmeter that generates a 4-20mA output. This includes various types of flowmeters such as differential pressure devices, magnetic flowmeters, and vortex flowmeters. The Contrec 202A operates solely on the power provided by the 4-20mA current loop, resulting in a maximum voltage drop of 2.5 volts across the input. As a result, it has obtained certifications for intrinsic safety according to European CENELEC standards and CSA standards for the USA and Canada.
This Flow Rate Totalizer offers full programmability to accommodate linear or square law input relationships, with options for setting the span, cutoffs, and conversion factors. All configuration parameters and totals are stored in a non-volatile memory, eliminating the need for internal batteries or external power sources. The unit also features high and low alarms through optically isolated solid-state relay outputs. Additionally, the high alarm output can be programmed to deliver a scaled pulse output proportional to the total.
The Contrec 202A is housed in a rugged IP67 (NEMA 4X) polycarbonate enclosure, ensuring complete watertightness. This design allows for direct mounting on the flow meter itself, or it can be panel-mounted or wall-mounted using a specialized universal bracket. The Flow Rate Totalizer comes standard with a wall mounting bracket, and a 2″ panel and pipe mounting bracket are available as optional accessories.
Experience the reliability and versatility of the Contrec 202A Loop-Powered Flow Rate Totalizer, an ideal solution for accurately measuring and monitoring flow rates in various industrial applications.
