What is it
The Proline Promag W 300 is an electromagnetic flowmeter (magmeter) designed especially for water and wastewater applications. It’s made to be robust in harsher environments, with a transmitter that is easily accessible. One of its distinguishing features is that it offers a “0 × DN” inlet/outlet run version (i.e. no required straight lengths upstream/downstream) and a “full bore” design that avoids constrictions and associated pressure loss.
Key Features & Benefits
Here are the main strengths and special features:
Feature |
Description / Benefit |
Accuracy |
The standard version gives ±0.5 % of reading plus ±1 mm/s. There's an optional “flat spec” version that improves upon that: ±0.2 % ±2 mm/s. |
“0 × DN / Full bore” |
This lets you install the meter directly after bends, T-fittings etc., with no need for long straight pipe runs upstream or downstream. That saves space, simplifies installation, and reduces pressure loss. |
Wide range sizes and flows |
It supports a large nominal diameter range (DN 25 up to DN 3000, i.e. ~1″ to 120″) and flow measurement range from about 0.5 m³/h up to 263,000 m³/h. |
Temperature & liner materials |
Different liner materials (hard rubber, polyurethane, PTFE) let you adapt to various media temperatures. For example, PTFE liner allows up to +90 °C in some cases. |
Pressure ratings & construction |
It supports up to PN 40 (Class 300 / 20K) in process pressure. Wetted parts are robust materials: electrodes in stainless steels, Alloy C22, tantalum; sensor housing materials are corrosion-protected. |
Operation, diagnostics, verification |
It has a compact, dual-compartment transmitter with up to 3 I/Os; backlit display with touch control; remote display option; various connectivity options (fieldbuses etc.). It uses Heartbeat Technology for verification, diagnostic tools, traceability. |
Suitability for harsh / hazardous environments |
Designed for water/wastewater plants, possibly submerged/underground installation; corrosion protection (per EN ISO 12944) etc. Approvals for drinking water; degree of protection up to IP68. |
