flowtherm Ex
_______________________________________________________________________________________
Multifunctional handheld unit with data logger for measuring flow rate,
flow velocity, temperature, pressure and other variables
in explosive atmospheres
Measured variables
 flow velocity
 volume flow/flow rate
 standard flow rate
 mass flow
 temperature
 other freely definable physical
values, in so far as measurable
or deducible with the sensors
suitable for connection
Media
 gases and gas mixtures
 liquids
Display units
 m/s, m³/h, l/min, l/s, kg/h,
ft/min, cfm
 ° C, ° F
 hPa, %RH, mA …
 m³
U425_flowtherm Ex_D_e_160729
Advantages
 for use in explosive atmosphere
ATEX category 2G (zone 1)
 wide variety of applications
due to the diversity of the sensors suitable for connection - FA,
VA, TA, Pt100, ...
 data logger for up to 40,000
values with date and time
 USB interface
 4-20 mA / 0-10 V input
 12 V power supply for nonHöntzsch sensors
 various measuring modes
 large Display
 easy-to-use, tactile key feedback
 with software HLOG II fully configurable on PC
 100 storable user profiles
 protection class IP65

Examples of application
 landfill gas, natural gas blower,
control measurement in explosive atmosphere, distribution
measurement of natural gas, …
 flow measurement in all
branches of industry, municipal
facilities and public authorities,
research and development
 measuring gas mass flow
 flow measuring in air, exhaust
air, process gases, particulate
and condensate laden emissions,
exhaust emissions, aggressive
gases with high working
temperatures
 measuring in conveying air
containing cement, carbon or
toner
 measuring tasks on filters and
ventilators
 system method to determine
flow rate or average flow
velocity of single measurements
