Description
AW-Lake VA flow monitors use a spring-loaded piston in a variable annular orifice, magnetically coupled to an external indicator, so they read accurately in any mounting position without straight pipe runs. They cover 0.1–150 GPM (0.5–550 L/min) of liquids and 2–1,300 SCFM of air or gas with ±2% of full scale accuracy, in aluminium, brass or stainless steel bodies rated up to 410 bar.
Versions include basic indicators, pneumatic meters, high-temperature meters to 315 °C, phosphate-ester meters, flow alarms with SPDT switches, flow transmitters with 4–20 mA, 0–5 V or pulse output, and portable hydraulic test analyzers that measure flow, pressure and temperature.
Argonmark Ltd supplies AW-Lake instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
