Description
The Hedland water-based flow meter is a direct-reading variable-area meter calibrated for water and water/oil emulsions (SG 1.0). Like the petroleum version it reads to ±2% of full scale with ±1% repeatability, installs in any position without straight runs, and resists shock and vibration; retaining parts are stainless steel for wet service.
Aluminium, brass and stainless steel bodies are rated up to 414 bar, sizes run from ¼ to 3 in, and reverse-flow by-pass and test-kit options are available.
Argonmark Ltd supplies Hedland 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.
