Wafer-Style Liquid Flow Meters


With enhanced features, Racine's RWL wafer-style liquid flow meters are a clear choice for flow measurement. The RWL series now includes updated electronics and an onboard display for improved performance and ease of use. Because the meters also include programmable software, 10-point linearization, and diagnostic tools, all easily accessible through the external keypad, they will provide superior performance in a number of applications including municipal water treatment facilities, cooling tower and water condensate, boiler feed water, chemical processing, and pool and water parks.

Racine's RWL vortex meters contain the smallest strut in the industry, producing accurate flow measurements with extremely low pressure drop. These meters are suitable for most low viscosity liquids, available as a loop-powered device with 4-20mA output, and fit pipe sizes from 1" to 3" (25mm to 76mm). They may be configured for 3-wire frequency pulse output as well. The meters have no moving parts and are virtually maintenance–free once installed.

Racine's vortex flow meters utilize ultrasonic sensing technology, allowing the meters to measure flow with an extremely small bluff body. As a result, system pressure drop and meter turndown ratio are greatly improved.
