Premier Control Technologies Flow, pressure, level and temperature solutions
High-pressure, multivariate flow measurement in real time
The Alicat MQ series of mass flow meter builds on the features of the standard instrument and can be used within higher pressure gas applications, ideal for when line pressures are between 160 and 320 psia (11 - 22 bara).
Flow rates are available ranging from 10 SCCM and going up to 3000 SLPM, combined with a 200:1 turndown ratio.
The mass flow meter is easy to use and is ready from the moment it is powered up (no warm up time) and the local display shows the live flow (mass and volumetric) as well as line pressure and temperature. The push button keypad allows for easy configuration changes such as engineering units.
As standard MQ series mass flow meters ship with an analogue output and RS-232 data communications, optional comms include Ethernet/IP, EtherCAT, DeviceNet, Profibus or Modbus (RTU and TCP/IP).
The data in the table below are standard configurations for models 10 sccm full scale through 20 slpm full scale. Please refer to the Mid-flow data sheet for full details.
| Mass Flow Accuracy at Calibration Conditions1 | ±0.6% of reading or ±0.1% of full scale, whichever is greater |
| Bidirectional Option1 | No additional uncertainties |
| Repeatability (2σ) | ±0.1% of full scale |
| Flow Measurement Range | 0.01–100% of full scale |
| Temperature Sensitivity | Mass flow zero shift: ±0.01% of full scale per °C from tare temperature Mass flow span shift: ±0.01% of reading per °C from 25°C |
| Pressure Sensitivity | Mass flow zero shift: ±0.01% of full scale per °C from tare temperature, per atm Mass flow span shift: ±0.01% of reading per °C from 25°C, per atm |
| Operating Temperature Range | −10–60°C |
| Temperature Accuracy | ±0.75°C |
| Operating Pressure Full Scale | 320 PSIA |
