Description
The Blancett B3000 is a flow rate indicator and totalizer for turbine flow sensors, reading 1 to 3,500 Hz pickup signals and showing rate and total together with 0.05% accuracy. The Base model covers standard metering, the Advanced adds two alarms and Modbus RTU, and the Solar model runs from an integrated photovoltaic cell.
It can be powered by a six-year lithium battery or the 4–20 mA loop, and comes in a NEMA 4X polycarbonate housing (intrinsically safe) or an aluminium explosion-proof housing with ATEX Ex d approval.
Argonmark Ltd supplies Blancett 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.
