Low Pressure Drop Mass Flow

Product catalog summary

Overview
The document introduces the MW 'Whisper' Mass Flow Meter and MCW 'Whisper' Mass Flow Controller by Alicat Scientific, designed for minimal system impact with low pressure drop and high accuracy. These instruments are suitable for applications requiring precise flow measurement and control, such as leak testing and gas analysis under soft vacuum conditions.

Specifications

Pressure Drop: As low as 4 mbar at full-scale flows.
Accuracy: 0.8% of reading (0.4% optional) + 0.2% full-scale repeatability, NIST-traceable.
Linear Range: 0.5-100% of full scale (200:1).
Multi-Gas Calibration: 98 gases preloaded, with COMPOSERTM gas composition firmware.
Portable Meter: Up to 18 hours of continuous use, rechargeable via USB.
Response Time: 5-ms meter response, 50-100 ms control response.

Features

Instant-on capability, ready in 1 second.
All flow data visible on one screen (flow, pressure, temperature).
Controller PID valve tuning for optimal speed and stability.
Digital and analog outputs available.

Options and Customization

Bidirectional Flow Calibration for full-scale readings in both directions.
Integrated Flow Totalizer for cumulative flow readings.
Downstream Valve for optimized control in vacuum or backpressure applications.
CSA Class 1 Div 2 (ATEX Zone 2) Classification for hazardous environments.
Backlit Color Display for low lighting conditions.
Industrial Communications: EtherNet/IP, DeviceNet, PROFIBUS, or Modbus.

Applications

Calibration of air sampling canisters across multiple ranges and gases.
Single-device leak testing and flow characterization.
Monitoring flows near atmospheric pressure or in airborne environments.

Additional Information
The document highlights the ease of use and rapid calibration capabilities of the devices, emphasizing their suitability for portable and real-time applications. The instruments are backed by a lifetime warranty, ensuring reliability and peace of mind for users.
