Output signal (instantaneous
flow rate output)
If 0-5 or 1-5 V DC is selected: Allowable load resistance 250 kΩ min.
Even if the measurement range is exceeded, output
remains less than 6 V.
If 4-20 mA DC is selected: Allowable load resistance 300 Ω max.
Even if the measurement range is exceeded, output
remains less than 24 mA.

), oxygen (for oxygen models only), fuel gas
13A (46 MJ), 100 % methane, 100 % propane, 100 % butane, and fuel gas 13A (45 MJ)
(selectable by the device keys)
User-specified gas type setup A gas type conversion factor from 0.100 to 8.000 can be specied using the keys.
Electrical connection Harness with dedicated connector (sold separately)
Connector: DF-11-10DS-2C made by Hirose Electric Co. Ltd.
Standards compliance EN 61326-2-3:2013, EN 61326-1:2013
(To be used in an industrial electromagnetic environment)
During EMC testing, the reading or output may uctuate by the equivalent of ±20 % FS.
Weight Approx. 800 g
*1. Gas types other than those listed above can be handled by using a conversion factor. For details, contact the azbil
Group.
*2. For fuel gas 13A, the device is calibrated based on the following two types of gases. If the composition of the fuel gas
that you use does not match either of these types, please contact Azbil Corporation.
Gas type (the following names are used by Azbil Corporation) Methane (%) Ethane (%) Propane (%) Butane (%)
Fuel gas 13A — 46 MJ 88 5.8 4.5 1.7
Fuel gas 13A — 45 MJ 88.9 6.8 3.1 1.2
*3. The ow rate range is for air. Because this device has a gas-type switching function, the device keys can be used to
switch from one gas type to another.
