Key Advantages for Engineering Systems
The Dwyer IEF-LN-10 transmitter provides distinct technical benefits over turbine or ultrasonic meters:
-
Zero Mechanical Wear: The absence of moving parts prevents impeller jamming from debris, significantly reducing maintenance costs.
-
Bidirectional Measurement: Capable of monitoring flow in both directions, perfect for complex piping networks.
-
Field Configurable: The built-in LCD allows engineers to configure pipe size, units, and zero-point calibration directly at the installation site without external tools.
-
Seamless Integration: Multiple output signals allow the transmitter to communicate directly with BMS, PLC, or SCADA systems.
Typical Applications
-
Chilled water flow monitoring in Chiller plants for BTU energy calculation.
-
Condenser water flow control in cooling tower systems.
-
Industrial water consumption management and leak detection.
-
Agricultural irrigation and large-scale water treatment monitoring.
