Expected Typical Specifications (for a GLA-300/HS / GLH-300 variant)

Below is a synthesized “likely spec sheet” combining known specs and reasonable inferences. Use this only for rough reference; always confirm from datasheet or manufacturer.

Parameter Typical / Expected Value
Measuring range (ullage) 0 to 50 m
Accuracy (RMS) ~ 5 mm (in slop / still-pipe mode)
Operating temperature –45 °C to +85 °C
Protection (ingress) IP66 / IP67
Ex rating Ex ia IIC T4 Ga
Antenna / sensor design Horn / PTFE plate isolator (for clean surface)
Material AISI 316L stainless steel, PTFE, etc.
Beamwidth / field of view Narrow beam (in standpipe mode, adapted to pipe diameter)
Cable interface / communication RS-485, possibly HART (for pressure)
Integrated pressure transmitter Yes (e.g. GT-450 equivalent)
Gauge socket requirement Usually ≥ 200 mm inner diameter for installation (or adapted for standpipe arrangement)
Weight On the order of tens of kg (typical GLA‐300 heads are ~17 kg)
