Practical, application-engineer answers on how radar, ultrasonic and 4G level instruments work, how to choose the right one, how to install them, and how to fix the common problems. Every guide links to the matching instrument and industry page so you can move from question to solution.
Frequency-modulated radar, beam angle, blind zone and why 80 GHz reads small tanks and dusty silos that 26 GHz cannot.
Radar, ultrasonic, guided-wave radar, hydrostatic and float — pros, cons and the best fit for each medium.
When non-contact radar beats ultrasonic on foam, vapours and distance — and where ultrasonic still wins on cost.
Match your medium, tank shape, temperature, pressure and output signal to the right technology and model.
Water, wastewater, chemical, grain, pump stations and oil & gas — the challenge and recommended instrument for each.
Narrow pipes, small dead-zone tanks, agitated vessels and uneven solid surfaces — what actually works.
Every parameter on a level transmitter datasheet explained — plus a specification template you can send to suppliers.
Mounting position, dead zone, foam and stilling wells — placement rules that decide whether it reads correctly.
Power, current-loop and Modbus wiring, and how to map measured level to the 4–20 mA output.
Zero & span on 4–20 mA / HART, Modbus scaling, radar false-echo learning, blind zone and a field checklist.
Spikes, false echoes, blind-zone alarms and small-tank errors — what the echo spectrum tells you and how to fix it.
Quick answers on specifications, outputs, certification and compatibility across the product range.
SIM & APN settings, solar power sizing, mounting, cloud platform binding, alarm thresholds and data-usage trade-offs.
Level-to-volume formulas, strapping tables for vertical, horizontal and rectangular tanks, and setting the 4–20 mA span by volume.
