1. July 27, 2007 — New Flow Switch With Temperature Sensor
   When a fluid based operating system requires sensing temperature and monitoring flow, Harwil Corp's newest product, a temperature sensing flow switch, the Q-12NT, fulfills the requirement. For systems involving boilers or chillers requiring temperature sensing while fluid flow is monitored, the new Harwil Q-12 NT flow switch senses temperature with accuracy of plus or minus 0.2 degrees C over a range from 0 to 70 degrees C. Rated at 50 watts, 120/240 VAC, the new flow switch controls on/off...
2. July 26, 2007 — Top or Side Mount Level Switch
   Submersible and easily mounted from top or side, Harwil Corp's L-40 N (Noryl) and L-40 VCR (Fortron - for corrosive fluids) reliably signals fluid level changes to on/off pump controls, alarms, or microprocessors. The loose pivot and long movement arm reduces effects of deposit and contaminant build-up. The Harwil L-40 SG level switch is also used for determining levels of two separate specific gravity liquids, such as detecting water in a gasoline or oil tank. The L-40 level switches are easy...
3. July 11, 2007 — Level Switch for Slurries
   When the pollution remediation system requires a level switch in particulate heavy sewage or slurries, the L-5 with Nema 4 cover or the L-5SS with a stainless steel cover level switches by Harwil Corp fit the specification. With one or two stainless ste ...
4. June 6, 2007 — Level Indicator for Slurries
   For medium slurries, particulate and corrosive chemical solutions, the L-30 Liquid Level Switch from Harwil Corp can dependably control pumps, alarms, or solenoid valves. Made from Noryl, the L-30N, for mildly corrosive slurries and Fortron, the L-30CR, for use with more caustic chemicals, these adaptable L-30 Level Switches can be mounted horizontally or vertically. Switching capacity is 15 amp, 120/240 VAC or Gold Contact "Dry" circuits for microprocessor connection. Flexible, elastomeric...
5. April 23, 2007 — Reliable Harwil Brass Flow Switch Services High Volume Systems
   High volume fluid flow - including environmental air scrubbers and ground clean up operations -- requires the heavy-duty, proven long-term performance of Harwil Corp's Q-5 brass flow switch or the Q-5SS in 316 Stainless Steel. The sturdy Q-5 with NEMA 4 cover performs reliably in municipal water supply systems, sewage treatment plants and large-scale irrigation systems. The Q-5 is adaptable to a wide range of pipe sizes and flow rate set points using variable shaft lengths and targets. In the...
6. April 20, 2007 — Buoyant Foam Filled Float
   The single switch pump up/pump down liquid level switch from Harwil Corp has been improved with the addition of a foam filled plastic float giving the switch greater buoyancy in low specific gravity liquids. The L-21N (Noryl) and the L-21VCR (for corrosi ...
7. February 9, 2007 — When the Water's Too Hot, Shut Off the Heater! Or, Sound the Alarm!
   The newest product introduction from Harwil Corp, the Temperature Sensor, signals a computer to activate an electrical response when fluids reach critical temperature settings between -20 and 200 degrees F. The low-cost Temperature Sensors fit into existing pipes or can be purchased in PVC Tee's. Four electrical connection options are available. Harwil Corp has engineers and knowledgeable sales staff ready to help customize the new high and low temperature sensitive switches to designer's...
