Thermal mass flow meters from AMS Instrumentation

AMS Instrumentation has released the ST75 Flow Meter for use in hazardous and explosive areas.
 

Designed for line sizes ranging from 6mm through to 51mm, the thermal flow meter has three outputs: a mass flow rate, totalised flow rate, and media temperature.
 

The media temperature compensation ensures meter accuracy in harsher environments up to ±2% of reading with ±0.5% repeatability.
 

The flow element contains no moving parts and uses platinum RTD sensors embedded in equal mass thermowells with microprocessors calibrated to laboratory standards.
 

The ST75 Flow Meter can operate in both low flow and high flow operations, ranging from 0.01 to 950 NCMH, depending on the size of the line.
 

The flow meter is remote mountable
 

Its transmitter has a full digital display and can be mounted up to 15 metres away from the sensor in the process piping and is connected via two .5 inch FNPT cables.
 

The ST75 is fully scalable and features thermal dispersion technology for direct flow measurement while eliminating the need for temperature sensors, flow computers and other meters.
 

The meter has a rugged sensing element constructed from 316 stainless steel and is enclosed in a dust and water resistant package designed for hazardous area installations.
