The DigiMax Pump Controller, manufactured by Wellmark Chemical Injection Solutions, is a versatile device designed to regulate chemical injection rates through intermittent motor control. It is available in two main versions: a 12VDC model optimized for off-the-grid battery-powered systems common in upstream wellsite chemical injection, and a 115VAC model for applications where grid power is available.
The primary function of the DigiMax controller is to precisely control chemical injection. It achieves this by managing the ON/OFF cycles of a pump motor. The controller offers both automatic and manual injection modes, allowing for flexible operation tailored to specific application needs. In Auto Injection Mode, users input desired injection rates in quarts per day, and the controller automatically calculates and implements the necessary pump cycle timing based on the pump's physical characteristics and motor specifications. Manual Injection Mode provides direct control over the pump's ON and OFF timing, enabling users to fine-tune injection rates and cycle timing manually.
A key feature is Temperature Injection, which incorporates a standard temperature sensor to enable temperature-switched injection. This allows for chemical savings by disabling flow when temperatures rise above a user-defined setpoint. The controller also includes Modbus RTU serial communication via a 2-wire RS485 connection, facilitating remote read/write control when integrated with a user's SCADA system. An onboard Human-Machine Interface (HMI) features an 8x2 LCD screen and four capacitive touch-sense buttons for local programming and interaction. For 12VDC versions, continuous Voltage Monitoring is provided, which can help predict solar application power failures when connected to a SCADA system. A Cycle Totalizer tracks the total number of pump cycles, aiding in injection rate analysis, and can be manually reset. To conserve power, especially in battery-powered systems, the screen backlight includes a timeout feature. All programming selections are non-volatile and retained even after power loss or a main power switch-off.
These specifications vary based on plunger size (1/4", 3/8", 1/2") and pin position (1, 2, or 3), and motor RPM (30 RPM, 64 RPM, 60 RPM).
The DigiMax controller utilizes capacitive-sensing buttons, requiring only a light touch for input, with an illuminating LED above each button to confirm registration.
