Latest New Breakthrough Technology!
Industry's First Self-Flushing Chemical Feed System!

Automatic Low Flow Vacuum Liquid Chemical Feeders (0.1 - 4 GPH)
» Note: The VRAD needs to be incorporated into the manual feed system above

A RELIABLE ALTERNATIVE TO METERING PUMPS

V-RAD (Vacuum - Revolving Automatic Doser)

Patent Pending

Designed for Feed Rates of 0.1 - 4 GPH
No vapor locking
SELF flushing design
Absolute control and reliability

	The V-RAD allows you to control timed pulses of liquid chemicals through a self cleaning, fixed orifice. The new V-RAD operates using a venturi nozzle to meter chemicals under vacuum. This type of design ensures there's no pressure on the chemical lines and a revolving orifice provides for constant self-flushing. View Brochure «» See Specs (PDF files)

Automatic Valves : Chlorination/Dechlorination/Ammoniation Auto High Flow (4 GPH - 7 GPM) Hydro Instruments Omni-Valve Series 110 is the latest in automatic chemical proportional feed control. From the most current technology in the PC Board, to the linear driven assembly (eliminating gears) to the six control options:
	1) Manual Control 2) Proportional (Flow) Control 3) Set Point (Residual) Control 4) Set Point (ORP) Control 5) Compound Loop (PID) Control 6) Step Feed Rate Control Features: • LCD Display • Broad range of chemicals and capacities • Password protected • Four push button user interface » Download Brochure (PDF)
