Draft Gauge

Boiler draft needs to be measured at seven different locations in a boiler. Accurate draft measurement can reduce emissions, improve boiler efficiency and reduce your energy bills.

Manas Microsystems manufactures Digital Draft Indicators / Transmitters. These digital instruments are more accurate and easier to read, compared to the mechanical gauges with analog indicators.

The mechanical gauges are of no use for control purposes as they cannot deliver any signal, while digital instruments can!

Manas Draft measuring instruments are very economical compared to sophisticated electronic gauge transmitters and are comparable in price with mechanical gauges.

In addition, the instruments can pay you back quickly in the form of saved energy due to perfect combustion.
