Omron, D6FZ-FGT Series

last update: April 20, 2016

Easy to Read

11-segment 8-digit LCD [First in the industry!*]

The characters are easy to read, and the total flow rate can be checked in a glance.

Display Reversal

You can reverse the display direction to match the installation direction.
Always use one of the specified installation directions.

High Accuracy

Highly Accurate Flow Measurements

An OMRON MEMS chip is used to achieve the highest accuracy in the industry* of ±2% F.S. (at 50 L/min or less).

Leakage Measurement

A high measurement accuracy of ±0.5% F.S. is achieved at a low flow rate of less than 50 L/min.
This allows you to identify the air flow that is discarded as leakage when machines are not operating to save money.

Zero Reset

You can use the zero reset to identify seasonal or day/night variations in the flow rates.

Other Features

Flow Straightener with Honeycomb Structure

A honeycomb structure effectively straightens the flow to keep pressure loss low.

Main Features

One analog output
Two pulse outputs
RS-485 communications
IP65

*1. Clean dry gas (Must not contain large particles, e.g. dust, oils, or mist.)
*2. The flow rates are converted for the following conditions. Standard flow rate (std): 1 atmospheric pressure (101.3 kPa) at 20°C (default setting) Normal flow rate (nor): 1 atmospheric pressure (101.3 kPa) at 0°C
*3. To prevent chattering, a judgement output is made when the judgement continues for one minute or longer.
*4. The accuracy will depend on the length of the straight pipe section. Refer to Flow rate accuracy characteristics for a length of straight pipe on page 12 for details.

*1. Up to 8 Sensors can be connected when the recording cycle is 2 seconds or longer; up to 4 Sensors can be connected when the recording cycle is 1 second.
*2. Data is automatically written to the SD memory card when the internal memory reaches its capacity and recording continues until the SD memory card capacity is reached. Recording stops if there is no SD memory card inserted, when the internal memory capacity is reached, or when the SD memory card is write protected. (Recording can be resumed after inserting an SD memory card and outputting the data to it by pressing a button.) The default is Continue Mode. Use the PC Software to change the recording mode.
*3. Recording of the latest measured values continues until the internal memory reaches its capacity. (If the internal memory capacity is exceeded, data is overwritten from the oldest data in the memory.)
*4. An alarm is output when the upper or lower limit of the air flow that was set in threshold setting mode is exceeded.
*5. You can temporarily read and write data with an SD card that complies with SD/SDHC card standards and was made by another company, but the SD card may suddenly not be recognized, preventing you from accessing the data.
*6. When mounting the Sensor with magnets, be sure to install it in a location where it will not be subjected to shock.
*7. A T-branch connector to connect to D6FZ-FC02.
*8. OMRON's XW4B-02B1-H1 Connector.
