Flexibility with Adjustable Liquid Flow Switches

Get state-of-the-art gas and liquid flow switch and liquid level control, applicable for hazardous environments, along with high temperatures, all with fast response times.

Sierra's InnovaSwitch™ flow and level switches represent advanced electronic technology in gaseous and liquid flow switching or liquid level control. InnovaSwitch was designed to meet a broad range of performance and environmental application requirements. The sensor and other wetted materials of this industrial liquid flow switch are 316L stainless steel and feature all-welded construction with no moving parts. The InnovaSwitch is easy to install and adjustable, giving reliable, low-flow, low-maintenance performance in the most demanding applications.

Liquid flow switch and electronic level detection is accomplished by using a high-resolution thermal differential technique. The sensor of our industrial liquid flow switches consists of a pair of matched Resistance Temperature Detectors (RTD's). One RTD is self-heated using a constant DC current. The other RTD of our low-flow switches is unheated and provides an accurate process temperature reference. The thermal differential created between the reference and the heated RTD pair is a function of the density and/or velocity of the media with which the sensor is in contact. The result is reliable, yet adjustable, liquid flow switch reading control in any heavy industrial application:

  • Pump protection
  • Safety spray nozzle monitoring
  • Cooling water/heat exchangers
  • Oil well system testing
  • Drain line flow
  • Relief valve monitoring
  • Seal detection
  • Chemical injection
  • Lubricant monitoring
  • HVAC monitoring
  • Reverse vent flow monitoring
  • Flow direction detection
  • Reverse pressure detection
  • Valve switching verification
