Past Product of The Month |
Enviromark is pleased to announce that Greyline has just launched an improved
Stationary Doppler flow meter called the DFM 5.0. This
replaces the DFM 4.0 the was introduced a year ago as an interim step
in the development of this technology.
The DFM 5.0 is now in production and the DFM 4.0 will be phased out over
the next 2 months, however service and replacement components for this
and other Greyline products
will continue to be available for the foreseeable future.
This is the first model of a brand new generation of flow and level instruments
from Greyline that will be launched over the coming year.
FEATURES
that offer enhancements over the DFM 4.0 and the DFM-IV:
- entirely new appearance with hinged cover to access electrical connections
- white backlit matrix display with adjustable brightness
- new 5-key menu system
- removable terminals for electrical connections
- menu language selection: English, French, and Spanish
- reverse flow measurement - a minus sign will appear during reverse flow
and the totalizer can be configured to decrement or ignore reverse flow
- 4-20mA, relays and totalizer are also configurable for reverse flow
- instrument auto-detects plug-in of optional extra relays and data logger
- optional data logger capacity increased from 50,000 to 2 million data points
- data logger output via USB to flash/thumb drives (so you don't
need to take a laptop for data retrieval) *** This
is a very important feature ***
Other enhancements that don't make the headlines but
substantially improve the user-interface:
- The totalizer works even if the DFM 5.0 is calibrated in velocity mode
- Data logging units are independent of calibration units
- Changing measurement units in the DFM 5.0 does not require a restart of the data logger
- Twenty-four hour flow reports are created independent of regular logging
- The DFM 5.0 will provide a flow reading as long as there is 1 bubble or
particle every ten seconds; if the concentration falls below that level,
the instrument reads zero
- The firmware has been configured to disregard non-flow related inputs (such as pipe vibration)
- A new sensor configuration has been created to enhance the ability of the instrument to read flow in difficult applications
