Description
The GF Signet 2100 is a compact turbine flow sensor for small lines: DN15 (½ in) pipe or ¼, ⅜ and ½ in tubing. It comes in two ranges, 0.38–3.8 l/min and 3–38 l/min, with ±3% of reading accuracy and ±0.5% repeatability, which makes it a good fit for chemical dosing and batching.
The body and rotor are PVDF with ceramic bearings for good chemical resistance, and the non-magnetic turbine works with clear or opaque liquids. It runs on 5–24 V DC, gives an open-collector pulse output, and is rated to 16 bar at 20 °C or 9.3 bar at 70 °C. Union ends accept barb, socket, fusion or NPT end connectors.
Argonmark Ltd supplies GF Signet instruments across Bangladesh — to pulp and paper mills, water and effluent treatment plants, chemical, textile, food and power plants in Dhaka, Chattogram, Gazipur, Narayanganj and beyond. Send us the model, measuring range, process connection, wetted materials and output you need, and we will confirm the right configuration, lead time and price.
