The FW Series of digital indicators is specially designed for computing and displaying total and instantaneous flow rates in liquid or gas applications. Versions are available for either pulse or analogue inputs, and a Batch controller is available for pulse inputs. Housed within a rugged, powder-coated aluminium enclosure that is suitable for direct mounting to a flowmeter, pipe, wall or panel. Units are also available mounted directly to the Turbine Liquid Flowmeters. Consult Sales for details. Units are available for pressure and level display, consult sales. |  |
