Digital 300B Series – 300 Vue

See Mass Flow in a Whole New Way!

 

The 300 Vue is the newest series of digital gas thermal mass flow instruments which provide accurate, fast, and convenient gas measurement and control.  The color touchscreen display allows the user to view and control the flow rate directly from the flow device. The main screen displays the flow rate, the flow setpoint (in case of controller), the units of measure, and the valve mode (Auto, Open, Closed). The display can also graphically display changes in flow over time. The B Series also features a USB port which is standard on all meters and controllers. The instrument can be installed and operating in seconds.

 

  • Color touchscreen display
  • Excellent accuracy ± (0.5% Pt + 0.2% FS)

200 Series

General Purpose – Excellent Stability!

 

The 200 Series, Teledyne Hastings’ flexible, general purpose series of mass flow meters and controllers, accurately measures and controls mass flow in a variety of applications. Featuring reliability and stability, the 200 Series is chosen for its very stable performance with varying ambient conditions. A wide choice of elastomer seals make this flow controller compatible with most gases.

The full scale range  is  specified by the end user. A NIST traceable calibration certificate is standard. Many corrosive gases and pressures up to 1000 psig are easily measured. Cleaning for oxygen service is available.

 

Low Pressure Drop, Large Flow Rates!

The HFM-200 LFE Series by Teledyne Hastings can be configured to accurately measure gas flow in a broad array of applications. The HFM-200 LFE meter has  flow ranges from 0-10 sccm to 0-15,000 slm, provides analog outputs, and is constructed of stainless steel.  The laminar flow elements (smooth, threaded or flanged) are available in various sizes from 3/8″ up to 8″.  Low pressure drops at full scale flow.

 

 

300 Series

All Metal, Fast Response, Low Flow Rates!

Featuring reliability and stability, the 300 Series is chosen for its fast response under a wide range of conditions. The metal sealed HFM-300 / HFC-302 meters and controllers have flow ranges from 0-5 sccm to flows of 0-25 slm. They are designed to accurately measure mass flow without corrections or compensations for gas pressure and temperature.

Corrosive gases and pressures up to 1000 psig are easily measured. No damage will occur from the use of moderate overpressures or overflows.

 

 

High Performance – Fast Response!

The HFM-301/-305/-306 meters and HFC-303/-307 controllers feature superior settling times and cover the medium to high flow ranges. The full scale range  is  specified by the end user. The devices provide analog outputs, are constructed of stainless steel, and can be configured to have either normally open or normally closed valves. These instruments are intrinsically linear and have an accuracy of better than ±1% F.S. (full scale).

Hastings mass flow instruments do not require any periodic maintenance under normal operating conditions with clean gases.

 

Digital 300A Series

All Metal, Fast Response, Tight Accuracy!

The HFM-D-300A / HFC-D-302A mass flow instruments have flow ranges from 0-5 sccm to 0-25 slm, use all metal seals, provide analog and digital outputs, and are accurate to better than ±(0.5% of reading + 0.2% of full scale) for full scale rates. Easy, user friendly digital communications with windows based software interface is available.

The Digital 300 Series uses a thermal-based mass flow sensor that is designed to provide exceptional linear response to changing flow rates. In addition, the electronics associated with each sensor are precisely tuned to give fast response time. The large diameter sensor tube allows the Digital 300 flow meter to have a small pressure drop.

 

 

Digitally Enhanced, Tight Accuracy!

Measuring a gas flow with a mass-based measurement provides accuracy, repeatability, and stability.  The A Series of the Digital 300 line covers ranges from 0-1000 slm (HFM-D-301A/HFC-D-303A), 0-2500 slm (HFM-D-305A/HFC-D-307A) to 0-10,000 slm (HFM-D-306A/HFC-D-308A). It can be configured with an optional IP-67 enclosure to provide protection against water and dust.

Self diagnostics of the sensor, valve, and overflow are included in the digital features. Also of interest is the auto zero feature which detects when the valve is closed and automatically resets the zero. These mass flow meters and controllers can store up to 10 calibrations of different ranges and gases.

The Digital 300 Series can operate with any power supply capable of providing 11 – 36 VDC between the high and low supply pins (e.g. bipolar ±12 VDC, ±15 VDC or unipolar +24 VDC).

Free Mass Flow Converter APP

 

Teledyne Hastings Instruments has developed a Mass Flow Conversion APP that allows to quickly convert flow measurement values from one set of units to another. The user also has the option to change the gas species and the reference conditions or STP (Standard Temperature & Pressure), which need to be specified when converting between mass flow units such as gm/s, lbs/hr and volumetric derived units such as slm, sccm, scfh, scfm, and so forth.

Four versions are available: iPhone, iPad, Android, and Web-based. The iPhone and iPad versions can be downloaded for free from the Apple iTunes Store. The version for Android can be obtained from Google Play. The web based version is available at www.massflowconverter.com.

 

Calibration and Repair Services

Periodic calibration on any instrumentation used in process control or research oriented projects is highly recommended!

5 Reasons for periodic recalibration:

  • Aging / Stress
  • Contamination
  • Tolerance shifts
  • Consistent quality of the end product
  • Reduced process inefficiencies
