Flow Control Equipment offers a verity of Fisher level controllers, sensors, and transmitters in new, new surplus, and remanufactured condition. We will take the time to ensure the right product and configuration is chosen for your application, whether it is in level, interface, or density control. By calculating the change in buoyancy forces based on your process conditions, we can simulate your application using our level controller calibration bench ensuring satisfactory controller performance. Often times people think their controller is the issue , when actually it is the density or volume of the displacer, or the wrong type of torque tube that is causing the problem. Let us help you avoid costly downtime by getting it right the first time!
