The Delta M VERSA-SWITCH? VS5100 is a versatile, field-adjustable thermal differential switch designed for precise monitoring of mass flow, liquid level, and temperature in both gases and liquids. Utilizing a dual RTD sensor configuration without a separate heater, it offers rapid response times—level detection as quick as 0.1 seconds and flow detection between 0.5 to 10 seconds, depending on the medium. With a wide operating temperature range from -100°F to +850°F, the VS5100 is suitable for a variety of applications, including foam control in tanks, water detection in fuel tanks, and chemical injection monitoring. Its user-configurable power options (110VAC, 220VAC, or 24VDC) and optional failure alarm diagnostics enhance operational flexibility and reliability. The VS5100 is backed by a two-year workmanship warranty, ensuring long-term performance and peace of mind.
