FKT 2DP1A-C Manometer and High Speed Meter
Measures Speed, Diff / Gage Pressure, Absolute Pressure, Temperature, Density, and Humidity
Specifications
Manual (PDF)The FKT 2DP1A-C is a portable multi-range manometer and air speed meter for high-speed flows where compressibility is a factor. This meter also allows for the simultaneous measurement and display of up to two independent differential pressures or speeds as well as concurrent measurement and display of atmospheric pressure, target gas temperature, relative humidity (RH) and density. Density is determined from the temperature, ambient pressure and humidity readings.
In conjunction with an optional flow probe such as Pitot-static, S type Pitot-static or Kiel, the FKT 2DP1A-C can make speed measurements corrected for true gas density, high speed compressibility effects and user-selectable ratios of specific heats for gases other than air. The instrument also interfaces with a PC using the FlowScan software suite allowing data logging and flow survey functions in airflow tests and can be configured as a component of a data acquisition system.
Designed and Assembled in the USA
Features
- Simultaneous measurement and display of
- Up to two independent differential pressures or speeds. This allows excellent flexibility in that multiple pressures/speeds may be measured simultaneously, or the transducer yielding optimum resolution for a particular application may be selected.
- Temperature.
- Relative Humidity.
- Atmospheric pressure (or absolute pressure).
- Real time display of true density including effects of temperature, ambient pressure and water vapor.
- Excellent accuracy.
- Extreme ease of use. The instrument was specifically designed to avoid menu driven operation, as this usually proves cumbersome and requires continual reference to the manual. Almost all required information is displayed concurrently through the use of a large 4 line LCD display.
- K factor (probe correction coefficient) for non-unity probes such as the S type Pitot-static probes used in dirty environments.
- English and metric units.
- Speed measurements are displayed with compressibility, temperature and humidity corrections. In conjunction with an optional flow probe such as Pitot-static, S type Pitot-static or Kiel (or multiple probes), up to two speed measurements, based on true gas density, can be displayed. Even the ratio of specific heats for the target gas is user selectable.
- Variable damping for measurements involving pulsating flows.
- Auto-zero function without disconnect. Internal valve removes pressure or speed offsets. Your reference level never changes ensuring unmatched accuracy and reliability.
- Over-pressure protection: If the applied differential pressure exceeds the transducer rating, the instrument will automatically enter the auto-zero cycle which will equalize pressure across the differential transducers reducing the possibility of damaging the transducer.
- Full data logging capability with optional FlowScan Software Suite. FlowScan performs logging; plotting, prompt driven duct Pitot probe surveys and even creates instant reports. FlowScan also has Excel connectivity to send the data directly to your worksheet.
