Harwil Corp.:
Temperature Sensing Flow Switch
Wednesday, November 21, 2007
The hot, new innovation from Harwil Corp combines the functions of temperature sensing and fluid flow switching. The newest switch senses temperatures from 0 to 70 C while switching an electrical connection based on fluid flow rates from 1-590 GPM in pipes from ¾ to 8 inches. The switches are made to OEM specifications for pipe size and flow rates. Two basic models are available: Noryl® for mild acid or base solutions or Fortron® for more corrosive fluids. Complete chemical resistance information is available on www.harwil.com. Electrical rating is 50 Watts, 120/250 VAC. The new compact switch mounts horizontally or vertically and can be ordered in a clear ¾” pre-barbed TEE. The temperature sensing flow switches are reliable and low-cost, like the traditional Harwil Corp line of flow and level switches. Technical assistance is available at Harwil Corp’s Oxnard, California based manufacturing plant.
