Volume flow measurement
By entering a k-factor under application settings, the EE600 is able to calculate the volume flow (q)
according to the formula:
q = volume flow [m3/h]
∆p = differential pressure [Pa]
k = k-factor
The k-factor is a characteristic theoretical parameter for each fan model, specified by the manufacturer
in the datasheet of the fan.
Note: If the data sheet of the fan manufacturer specifies a different method or unit of calculating the
volume flow, the k-factor must be converted accordingly to fit the above formula.
For example: If the k-factor (kspecific) in the data sheet of the fan manufacturer applies for volume
flow calculation in m³/s it has to be converted as follows:
Fig. 6 Application settings - volume flow rate measurement
The calculated volume flow (q) is available via BACnet or Modbus protocol in four different units: m3/h,
m3/s, ft3/min, l/s.
The default air density (ρ20) value at standard conditions is defined as follows:
Air density (ρ20): 1,204 kg/m3 @: T = 20 °C (68 °F), p = 1013 mbar (14,7 psi)
If the air density deviates from standard conditions, a compensation for the calculated volume flow is
necessary.
By entering the specific air density (ρ´) [kg/m3] at the operating point, the EE600 applies a compensation to the calculated volume flow (q´) according to the formula:
q’= volume flow at specific density [m3/h]
∆p = differential pressure [Pa]
k = k-factor
ρ´ = specific air density [kg/m3]
ρ20 = air density at 20 °C (68 °F) [kg/m3]
Air velocity measurement
By entering a k-factor and the dimensions of the duct (round or square), the EE600 is able to calculate
the air velocity (v) out of the volume flow (q) and the area of the duct.
12
v = air velocity [m/s]
q = volume flow [m3/h]
A = Area [m2]
User Manual EE600 Differential Pressure Sensor
Page 13
Details for k-factor see application settings for volume flow measurement.
Fig. 7 Application settings - Air velocity measurement
The calculated air velocity (v) is available via BACnet or Modbus protocol in two different units: m/s and
ft/min.
Details for setting air density (when deviating from default air density at standard conditions) see application settings for volume flow measurement.
Filter monitoring
By entering filter limits for differential pressure, the EE600 is able to calculate a contamination level for
the observed filter in order to plan for maintenance purposes.
Fig. 8 Application settings - Filter monitoring
For the given application setting (∆p change filter = 800 Pa, ∆p new filter = 100 Pa) a measured differential pressure at the filter of ∆p = 450 Pa, would mean a contamination level of 50 %:
The filter contamination level is available via BACnet or Modbus protocol expressed in percentage [%].
User Manual EE600 Differential Pressure Sensor
13
Page 14
Level indicator
By entering the density [kg/m3] of a fluid the EE600 can act as a level indicator. The differential pressure
level measurement uses the pressure values and the specific weight of the fluid to represent the level in
a tank (see „Fig. 14 Mounting examples“).
Fig. 9 Application settings - Level indicator
h = Level (cm)
∆p = Differential pressure (Pa)
ρ = Density of fluid (kg/m3)
g = Gravitational acceleration (9,81 m/s2)
By applying the positive pressure connection into the tank, the user can measure the height of the column of that fluid.
The level measurement is available via BACnet or Modbus protocol in two different units: cm and inch.
The maximum measurable level is limited by the highest differential pressure range 0…10000 Pa.
For example, for water with density 998 kg/m3, at 10000 Pa the maximum height is 102 cm (40 inch).
5 Installation
• Mount the EE600 onto a vertical, smooth surface.
• Important: The pressure connection nipples must point downwards.
• Avoid installation close to heaters and sources of strong electromagnetic interference.
• Insert the cable for supply voltage and output signal through the cable gland and connect it to the
spring terminals according to the wiring diagram („Fig. 3 Connection diagram“).
• Important: Make sure that the connecting cable or wires do not impact with the push buttons in order
to prevent unintentional trigger of the span or zero point adjustment.
• Close tightly the cable gland. This is essential for the compliance with the IP65 / NEMA4 protection
class of the EE600 enclosure.

• Install first the pressure connection nipples (included in the scope of supply) onto the duct.
Use a Ø 7.5 mm drill.
• Connect the pressure hose (included in the scope of supply) first to the EE600 and then to the nipples
at the duct. Route the pressure hose for avoiding sharp bends which might lead to the hose
obstruction („Fig. 13 Pressure hose route“).
Fig. 13 Pressure hose route
Important: Make sure to connect the higher pressure at the “+” pressure connector and the lower
pressure at the “-“ pressure connector. Inverted connection leads to “out of range” information on the
optional display and at the analogue outputs, see „4.1.6 Outputs“ and „7.2.3 Out of range“.

6 Maintenance and service
EE600 does not require any special maintenance, nevertheless it is recommended to perform a zero
point adjustment every 12 month. If needed, the enclosure may be cleaned and the device may be
re-adjusted as described below.

6.1 Cleaning
Use a damp soft cloth to remove deposits of dust or dirt from the exterior of the device and from the
display. Do not attempt to clean the interior of the device. Do not use any solvents, alcohol or abrasive
cleaning agents.
6.2 Repairs
Repairs may be carried out by the manufacturer only. The attempt of unauthorised repair excludes any
warranty claims.
6.3 Readjustment of EE600
A periodical readjustment of EE600 might be required by the regulations of certain industries or by the
need of best long-term measurement accuracy. The zero point and the span point can be adjusted with
push buttons on the EE600 electronics board.
For adjustment the device must be powered and the enclosure cover removed. Consequently, the
adjustment may be performed by authorised staff only, observing the handling of electrical sensitive
devices (ESD).
6.3.1 Zero Point Adjustment
16
The zero point adjustment is used to correct an eventual zero point deviation.
a. Remove the tubes from both pressure connections of the EE600. By this the pressure equal on
both connections.
b. Press “zero point” button 1-2 sec. (see „3 Product Description“).
c. The successful zero point adjustment is confirmed by the green LED turning on for 2 seconds.
d. The red LED turning on for 2 seconds indicates that the zero point adjustment did not succeed. In
this case repeat b.
User Manual EE600 Differential Pressure Sensor
Page 17
e. The zero point adjustment (b.) may not succeed because of a deviation higher than 5 % of the
original full scale of the device. This is 50 Pa for the 0 – 1000 Pa range and 500 Pa from the 0 –
10000 Pa range. In such a case, the zero point adjustment can be forced by pressing and holding
the zero point button for min. 10 sec.
f. The successful zero point adjustment is confirmed by the green LED turning on for 2 seconds.
6.3.2 Span Point Adjustment
The span point adjustment is used to correct an eventual deviation of the span value.
Important:
Make sure to perform a zero point adjustment as above before any span point adjustment.
a. Connect the differential pressure reference device/calibrator to the EE600 and set it according to
the EE600 span value to be adjusted.
b. Note: The span value has to be set according to the selected measurement range.
Example:
Analogue version: (see „4.1.1 Select the measurement range with S1 and S2“, Tab. 1)
EE600-HV53A7, S1 = 0, S2 = 1, span value = 5000 Pa
Digital version: EE600-HV52J3, span value = 1000 Pa
EE600-HV53J3, span value = 10000 Pa
Observe the operation manual of the reference device.
c. Press the span point adjustment button (see „3 Product Description“).
d. The successful span point adjustment is confirmed by the green LED turning on for 2 seconds.
e. The red LED turning on for 2 seconds indicate that the span point adjustment did not succeed. In
this case repeat b.
f. The span point adjustment (b.) may not succeed because of a deviation higher than 5 % of the
original full scale of the device.
This is 50 Pa for the 0 – 1000 Pa range and 500 Pa from the 0 – 10000 Pa range. In such a case,
the set point adjustment can be forced by pressing and holding the span point button for 10 sec.
g. The successful span point adjustment is confirmed by the green LED turning on for 2 seconds.
6.3.3 Return to Factory Adjustment
a. Press and hold simultaneously both “zero” and “span” buttons for 5 sec.
b. The successful return to factory adjustment is confirmed by the green LED turning on for 2 seconds.
c. The red LED turning on for 2 seconds indicates that the return to factory adjustment
did not succeed. In this case repeat b.
Important:
Return to factory adjustment affects both zero and span.
