Oval Gear Flowmeter Model DON

Description

Oval gear flowmeters are categorized as positive displacement
flow technology. When liquid flows through this type of positive
displacement flowmeter, two oval geared rotors measure a constant
volume per rotation within a precisely machined measuring chamber.
With each rotation, a constant volume of liquid is measured. The
rotation of the oval gears is sensed via magnets embedded within
the rotors. These magnets transmit a high resolution pulse output.
The output signal can be processed externally via a remote display
controller or PLC or via a variety of output/display options available
as accessories attached to the flowmeters.

Operation:
Liquid travels around
the crescent shaped
chambers created by
the rotational movement
of the rotors

Liquid in transit

Flow

Liquid entering the
measuring chamber

The positive displacement flow technology allows for precise flow
measurement of most clean liquids regardless of the media's
conductivity. Other liquid properties also have a minimal effect on
the performance of this type of meter. Flow profile conditioning is
not required, as with alternative flow technology options, making
oval gear installations simple to install in tight spaces and at a
economical price.

Areas of Application

Suitable for viscous, non abrasive, clean liquids like:



Petroleum



Grease



Pastes

●
●

Oil
Fuels

●
●

Aluminum body meters are compatible with fuels, fuel oils, & other
lubricating liquids. In addition to lubricating media, stainless steel
flowmeters are suitable for most products and chemicals.

Output Types

Reed Switch Pulse Output (.. R0 / RE)

The reed switch output is a two wire, normally open, SPST, voltage
free contact ideal for installations without power or for use in
hazardous area locations where Intrinsically Safe (I.S.) is required.

Note: when using the reed switch output, the liquid temperature must
not change at a rate greater than 18 °F per minute.

Average switching life of reed contact (MTTF):
Max. Load (100 V / 10 mA) 5 x 105 switching cycles

Min. Load (<5 V / 10 mA) 5 x 108 switching cycles
Power supply: max. 30 VDC, max. 200 mA

Hall Sensor Pulse Output (.. H0/HE)

In the electronics options H0/HE, a Hall Effect sensor is combined
with an active push-pull output. The signal output is actively switched
either to +Vs or to ground. No additional external circuit is required
(e.g. pull-up resistor). The "high" signal is approximately equal to the
supply voltage +Vs and the "low" signal is approximately 0 V. The
electronic utilizes a 3-wire connection with an external supply voltage
of 8 ... 30 VDC. The electrical load may be optionally connected to
the supply voltage or to GND. Maximum output current (current
source or sink): 100 mA (short circuit protected). In addition to the
Hall sensor, this option is equipped with a Reed switch which works
the same as option R0/RE.

No responsibility taken for errors;
subject to change without prior notice.

www.koboldusa.com

Hall Sensor Pulse Output (.. HU)

Like option H0, except an NPN output in place of the
push-pull output and a supply voltage of 5-30 V

DC.

Hall Sensor Pulse Output, (.. B0/BE)

Like options H0/HE; however with bipolar sensors and
alternating polarized magnets. This option is used for
pulsating flow, but is not equipped with a Reed switch and
has half the k-factor value as compared to H0/HE.

High-Resolution Hall Sensor Pulse Output, (..G0/GE,
..K0/KE)

Like options H0/HE; the models DON-x05 and DON-x10 can
be supplied with four times the pulse count per volume unit
and models DON-x05...x20 with double the amount of pulses
(K0/KE) (see table «Output Pulse Resolution» on the following
pages).

Quadrature Hall Effect Pulse Output (..D0/DE)

The DON with option D0/DE provides two independent Hall
sensors. They are arranged to give separate outputs out of
phase with one another.
The QUAD output is mostly suitable for detecting bidirectional
flows (detection of flow direction) or where a redundant signal
is desirable. Maximum output current per channel (current
source or sink): 100 mA (short circuit protected).

Analog Output (..L0/LE)

The options L0 and LE (Ex) are available with a loop-powered
4-20 mA output. The loop must be powered with an external,

16...32 VDC power supply. The maximum resistance of the
series loads (PLC analog input / display electronics) depends
on the magnitude of the supply voltage and can be calculated
as follows:
Max. load [Ohm] = (+Vs – 9 VDC) / 0.02 A [Ω]
Example: +Vs = 32 VDC = > max. load = 1150 Ω

+Vs = 16 VDC => max. load = 350 Ω
The load can be inserted at any point in the current loop,
observing correct polarity.

Mechanical Totalizer (..M4)

The DON-x20 .. through DON-x60 .. are available with a 4-digit
resettable totalizer and indication of accumulated total value.
The motion of the rotors is transmitted to the mechanical
register totalizer via an interfacing reduction gear train and
dynamic seal assembly. Option M4 is also optionally available
in liters.

Body Material: Enameled Die-cast Aluminum,
Powder-coated
Protection: IP 65

Ambient Temp: 32...140 °F
Media Temp: -4...176 °F

Recommended Filtration Requirements:

DON-x05 ... DON-x15 < 75 μm (200 mesh)

Pressure Drop Limit Versus Flowrate

The curves above represent the pressure drop for standard cut oval rotors. Special cut rotors, option "Y" have alternate tooth relief
which effectively reduces the pressure drop by 50%. When sizing a meter, be sure your selection falls below the 1 bar (14.5 PSI)
maximum allowable pressure drop line on the graph.

Special Cut Rotors for Higher Viscosities

For viscosities > 1000 cP, special cut rotors (option: "Y") are
normally required to keep the maximum pressure drop from
exceeding acceptable levels. This option applies to DON-x15
and larger sizes. For higher viscosities, the flowmeter max.
flowrate is derated according to the table above.
Example:
DON-x25G measuring viscous oil at 8000 cP:
max. flow of 40 GPM x 0.5 = 20.0 GPM new max. flow rate.
