Toshniwal Industries Guided Wave Radar Level Transmitter TLR1000G1

TLR1000G1 Guided Wave Radar Level Transmitter

TLR1000G1

TLR1000G1 guided wave radar level transmitter measures continuous level in conductive and non-conductive liquid applications using TDR technology. It guides high-frequency microwave impulses along a steel cable, rod or coaxial probe and calculates level from pulse travel time. Also, it supports 4–20 mA / HART output, two-wire or four-wire versions, IP67 protection and measuring ranges up to 30 m depending on probe type. As a result, it suits liquid level applications where steam, buildup, foam or condensation may affect simpler measurement technologies.

  • TDR-based level measurement
  • Cable / rod / coax probe options
  • 4–20 mA / HART output
  • Up to 30 m range
  • IP67 protection

    Frequently Asked Questions

    TLR1000G1 is used for continuous level measurement of conductive and non-conductive liquids in suitable tanks and process vessels.
    It uses TDR technology, also known as Time Domain Reflectometry. High-frequency microwave impulses travel along a cable, rod or coaxial probe and reflect from the product surface.
    The model supports cable probe, rod probe, double cable probe and coaxial waveguide options in SS316 material.
    The measuring range depends on probe type. Cable probe supports 0–30 m, rod probe supports 0–6 m, and coax probe supports 0–3 m.
    Yes. It supports 4–20 mA / HART output in two-wire and four-wire versions.
    The process temperature range is -40°C to +200°C, depending on selected seal and configuration.
    The instrument has IP67 protection.
    It can work in suitable liquid applications where steam, buildup, foam generation or condensation may affect other level technologies.
    Users should check liquid type, tank height, measuring range, dielectric behavior, probe type, pressure, temperature, foam, vapor, buildup, process fitting, output requirement and power supply.
