IVEK Maintainer Metering System Controller Rotary Liquid Model#- Maint-165-B This is extremely hard to find Maintainer from IVEK. This does very specialized work and would normally cost a TON. But not with me. You can get this for cheap with me. From Manufacturer: Overview: The Maintainer Controller Module is a component in a rotary liquid metering system consisting of a Controller, Motor/Base and Pump Module(s) providing automatic continuous set-point control of process variables in chemical or biological systems. The controller is easily programmed by the user and can be interfaced directly with a process instrument such as a pH meter, or other analog output process signal in order to provide set-point control. It is designed to provide a metering rate proportional to the process deviation from a set-point, virtually eliminating overshoot and generally enhancing process stability. Features: Digital control of Stepper Motor Minimal maintenance System Response Factor (SRF) multiplier switch Auto/Manual switch Direct/Inverse switch Slope Multiplier to select RPM range NEMA 4X enclosure available Set-point control of process variables Accepts analog control signal: 4-20mA CE Certificate available This controller used with the following modules: Microspense AP Motor/Base Module Heavy Duty Motor/Base Module Split Case Pump Module Micro Rotary Pump Module Disclaimer - Seller not responsible for any damage to life, limb, or property due to this device.
