Ultra-High Pressure Gas Mass Flow Meters and Flow Controller from Sierra Instruments
The SmartTrak 100 HP from Sierra Instruments offers precision flow measurement and control at very high gas pressures is among the most challenging applications in the flow industry.
It has been designed to overcome the challenges of leaks, gas behavioral changes, and unpredictable valve control that can all lead to reduced performance. The 100HP combines the high performance of the SmartTrak® with a wider, more robust flow body, all-welded sensor seals, an innovative new valve design called ValFlex™, as well as state-of-the-art high pressure calibration facility, resulting in an instrument with increased application flexibility and accuracy in high pressure gas flow control applications.
To increase valve performance and accuracy under high pressures, Sierra’s proprietary ValFlex™ valve seat technology uses a flexible, high-impact, carbonreinforced polyamide valve seat material to assure smooth interaction with the valve orifice. The result is precision control over a wide range of flows from 100 sccm to 20 slpm with an industry leading leak-by as little as 4 sccm at 5000 psid (345 bard), dependant on the orifice used.
To prevent the deforming under hig pressures the 100HP uses harder, denser seals to minimise gas permeabiity.
The 100HP delivers precise, high pressure measurement and control, each unit is calibrated to NIST traceable high-pressure calibration, using a gas booster, high-pressure accumulator tanks, and mirrored precision pressure gauges, yielding highly accurate inlet and outlet pressures to match the customer’s application perfectly.
Sierra Instruments has designed the 100HP as a versatile solution for the most challenging highpressure gas mass flow applications.
