Impulse - Model TXXXX Series -Guided Wave Radar Meter

Easy to install, Easy to use

• Easy navigation
• 2-wire, HART or Modbus digital communication for Class I, Div. 1, Zone 0 installations
• Push-Button configuration or HART communications
• No calibration or Level changes needed
• System configuration asks only those basic questions that pertain to your selected level measurement type, and in plain language. You will be expertly measuring the process level within minutes
• Dual Compartment housing separates customer wiring terminals from the Intrinsically Safe electronic circuits, display and keypad

Dependable performance

• Sensor designs that will tame even the most difficult level measurement application
• Despite disturbances such as agitated, or irregular surfaces, foam or coating of the probe, the Impulse Guided Wave TDR will continue to provide reliable and accurate measurements.
• Unaffected by changes in density and dielectric properties, dusts, vapor, and turbulence
• Low dielectric measurements down to a dielectric constant of 1.4, suitable for LPG/LNG service.
• Hazardous approvals Intrinsically Safe, Explosion Proof and Non-Incendive approvals

Application versatility

• Probe Type and Material selections for all applications Ideal for level measurement of Liquids and Slurries.
• Ideal for replacement of costly mechanical displacer systems
