FISHER DLC3100 Level Controller | Ultrasonic, Non-Contact, 4-20mA+HART, Single Point

FISHER DLC3100 Level Controller | Ultrasonic, Non-Contact, 4-20mA+HART, Single Point

FISHER DLC3100 controller specifications. Ultrasonic level controller, non-contact, 4-20mA+HART output, single point control, tank and pump applications.

Product Overview

The FISHER DLC3100 is a digital level controller designed for tank and pump control applications. It utilizes non-contact ultrasonic technology to measure liquid or solid level and provides a 4-20mA analog output with HART digital communication. The controller includes configurable dual setpoint relays for high/low alarm or pump control functions, making it suitable for simple point-level monitoring and control.

Important Notes

1. This is a non-contact ultrasonic​ device; performance can be affected by foam, heavy vapors, dust, or extreme turbulence.

2. The 4-20mA output is proportional to the measured level or distance.

3. Relay functions (high alarm, low alarm, pump lead/lag, etc.) are fully configurable via the local interface or HART communicator.

4. For hazardous area​ installations, verify the specific certification suffix on the device label (e.g., DLC3100***).

5. Proper mounting location​ is critical; avoid obstacles in the sound beam path and maintain minimum dead band distance.
