商品説明The FL-9000 Series flowmeter are rugged, low-cost direct reading industrial class flowmeters that are simple to install. They can be mounted (installed) in any position from vertical to horizontal without costly flow straighteners or other special plumbing. Constructed of high impact polysulfone plastic, the product line offers excellent structural integrity and chemical compatibility with a wide range of industrial chemicals. FL-9000-ACL/DCL The AC and DC powered flow switch modules consist of a latching relay circuit housed in a sealed polypropylene enclosure. The modules have a normally open dry relay contact that can be used to directly control alarms, warning lights, relays or be used to interface to a PLC. The relay will be latched on as the magnet inside the flow meter passes by the module, and remain latched on until the magnet passes in the other direction or power is interrupted. The set-point is adjustable from 0 to 100% of full scale. FL-93/96/ 97/98/9900 FL-9000-RA/RB/RC The reed switch modules are housed in a sealed polypropylene enclosure. The reed switch module does not provide the latching function like the AC and DC powered units. When the magnet inside the flowmeter comes within proximity of the module, the reed switch will change state. The setpoint is adjustable from 0 to 100% full scale. Two reed switches providing low flow and high flow set points may be installed on a single flowmeter.
