Plasto-O-Matic Chemical Flow and Level Indicators offer a safe and economical means of indicating flow, clarity, or exact level of extremely corrosive and ultra-pure liquids. Materials Of Construction: A wide choice of plastic indicator end materials is offered to assure maximum chemical compatibility.
Polypropylene, PTFE or Kynar. Standard O-ring seals on Series “GX” indicators are either Buna-N or Viton. On Series “GX”, “GYW” indicators. Viton O-rings are standard. Stainless steel fasteners are standard on all flow indicators. The transparent inner cylinder walls used in the Series “GY”, “GYW” indicators are Pyrex. The transparent outer cylinder walls used in all PLAST-O-MATIC indicators are high impact strength acrylic.
Series GL level indicators utilize a double-wall construction to indicate the level of highly corrosive or ultra-pure liquids compatible with Pyrex glass. They cannot be used with hydrofluoric acid or sodium hydroxide as they will etch the Pyrex cylinder wall. They are available with either PVC, natural polypropylene or PTFE ends in nominal lengths of 1, 2, 3, and 4 feet. FKM seals are standard. Pipe sizes are 1/2" and 3/4" NPT. BSP (British Standard Pipe) threads are also offered. Consult page 4 for pressure and temperature specifications.
Series SWT contains a snap-action electric switch with three terminals. One is common, one is normally-open, and one is normally-closed. The normally-open switch will close upon reaching the set pressure, and the normally-closed switch will open when set pressure is reached. Set pressure can be reached by higher system pressure falling to the set value, or when lower system pressure rises to the set value.
Series FS pre-set Flow Switch is available in PVC or CPVC, with flow rate range from .7 - 25 GPM. Switches offered from 5 VDC to 240 VAC.
Series FSA adjustable Flow Switch is available in PVC or CPVC, with flow rate range from 8 - 1900 GPM, designed for pipe size 1" through 10". Offers continuous adjustment during operation; SPDT 15 amp switching capacity model or Dry Computer/PLC Interface model.
Series LLS with pivot pin design is 1 1/4" x 1/4"x 1/2" reducer bushing for through wall mounting. SPST reed switch for 120/240 VAC 50 Watt power or optional DC dry circuit for computer/PLC interface
Series FPS provides low voltage signal and visual indication when liquid is present in non-pressurized piping or components. Designed for one-time use; requires simple sensor replacement after the sensor is triggered. In less aggressive chemical applications, the probes may be cleaned and re-used. Suitable for any conductive liquid with a resistance less than 3 Megohm.
