General Description
The EDM turbine flowmeter measures the flow of water and low viscosity
liquids ranging from 0.3 GPM to 300 GPM. Its replaceable lithium
battery powers an onboard rate meter/totalizer allowing installation
in virtually any location, regardless of power availability. Results
are displayed on a highly visible LCD readout. Except for units
with a flow rate transmission feature, the EDM is also FM approved
for operation in Class I, II, and III Division 1 hazardous areas.
Versatile and easy to use, the EDM’s modular design allows
us to offer a variety of electronic modules which further enhance
its versatility. Available are options for a remote display, a frequency
output, and a 4-20 mA analog transmitting output. Nylon, aluminum,
PVC, PVDF or stainless steel body construction make the EDM compatible
with a wide variety of process media.
Improved Computer Electronics
The upgraded computer electronics features 1 rate and 2 totalizing
displays. Standard measuring units are field switchable GPM or LPM.
The ability to store two field calibrations allows the user to freely
switch 3 different liquid viscosities with the same flowmeter.

- Economical PVC Construction
- Flowrate Indication with Resettable and Non-Resettable
Totalizers
- Flow Ranges 1-10 GPM through 20-200 GPM Water
- Lithium Battery Powered Indicator Requires no Local Supply

The EDM series water flowmeter is excellent for accurately
totalizing water and other low viscosity liquids. It features
an economical PVC body and lithium battery powered LCD display.
The display has a resettable batch totalizer and a nonresettable
grand totalizer, as well as rate indication. These displays
are accessed by a toggle pushbutton on the face. The EDM is
factory calibrated for water flow. This calibration is valid
for low viscosity liquids up to 10 centistokes viscosity.
For higher viscosity liquids, a field calibration mode exists
allowing the user to dispense a known volume of liquid in
order to calibrate the EDM’s computer for the higher
viscosity liquid.
The EDM electronic water meter is available
in line sizes from 1/2 to 2 inches. Fittings available are
PVC socket or NPT threads. The EDM series combines economy
with a full featured electronics making it an excellent and
economical replacement for metal body mechanical water totalizers.
Onboard Display Features
Flowrate indication, one user resettable
batch totalizer, one non-resettable grand totalizer, field
calibration routine for higher viscosity liquids (100 cPs
Max.). |
