1. System overview
A measuring point consists of the following components:
•Evaluation unit (MSE 300) in the DIN Rail housing or field housing
•Weld-on sensor socket with air purge connection
•Sensor
•C1- or C3-Box (optional)
The system can be equipped with up to three sensors. Depended on the number of sensors, different
C-Boxes (C1, C3) should be use.

2. Function
•The PicoFlow is a measuring system which has been specially developed for measuring the quantity of
pneumatically conveyed solids.
•It is used for very small solid / air ratios.
•The intrusive sensor probe is made of solid stainless steel and has an additional ceramic coating.
•The sensor works on electrodynamic principles. Each particle flowing past the probe generates a charge
signal. The sum of all individual signals is temporally proportional to the quantity of solids.
•Each measurement point consists of a sensor and a evaluation unit.

3. Safety
The PicoFlow was designed, built and tested for safety and is shipped in this condition. Components within the
supplied system could be hazardous if not unpacked, installed, connected and commissioned by authorised
qualified persons. All operating instructions must be read, and understood, before handling the system. Failure to
do so will cause the warranty to be revoked.
3.1 Normal use
•The measuring system may only be installed for measuring the low flow rate in metallic pipes.
•Only original spare parts and accessories of ENVEA Process must be used.
3.2 Identification of hazards
Possible hazards, when using the measuring system, are marked by the following symbols:
Warning!
•This symbolises a situation where personal safety is at risk if used in an improper manner.
Attention!
•This symbolises the possible damage to the system, if used in an improper manner.
3.3 Operational safety
•The measuring system must be installed by trained and authorised personnel only.
•In case of maintenance-work on the pipe or on components of the PicoFlow, make sure that the piping
is in unpressurized condition.
•Switch off the power supply for all maintenance, cleaning or inspection works on the sensor or on
components within the PicoFlow. Follow the notes of the chapter maintenance.
•Caution, if welding is required on the pipe, remove sensor.
•The components and electrical connections must be checked for damages regularly. If a damage is
found, it is to be repaired before further operation of the instruments.
3.4 Technical statement
•The manufacturer reserves the right to change any technical data concerning technical developments,
without prior notice. If any queries arise, ENVEA Process will be happy to inform customers of any
possible changes made.
3.5 Reliability
For any additional information concerning product reliability, please contact ENVEA Process.

4. Mounting and installation
4.1 Delivery range:
•Evaluation unit (MSE 300) in the DIN Rail housing or field housing
•Weld-on sensor socket with air purge connection
•Sensor
•Operating instructions
•C1- or C3-Box (optional)
4.2 Auxiliary
•Drill Ø 27 mm for steel
•36 mm open-end spanner for sensor-hexagon
•approved tools for the electric connection
4.3 Mounting of the sensor
Proceed as follows to install the sensor:
•Decide on the installation position on the pipe. It should be installed from the top on horizontal or
angled pipelines.
•The probe length should be at least half of the diameter. The maximum probe length is 450 mm.
•If required, up to three sensors can be installed in one line.
- In a two-sensor application, the sensors are used in a 90° offset.
- In a three-sensor application, the sensors are used in a 120° offset.
•The distances apply to vertical and horizontal installations.
•Ensure that the measurement point is an adequate distance from valves, manifolds, blowers and bucket wheel
feeders and other measurement ports such as those for pressure and temperature sensors, etc. (Fig. 6).

•Weld the sensor accommodation to the duct. The plastic inlay
and the air connection must be removed before welding.
•Drill the hole of 27 mm diameter through sensor accommodation.
Ensure that the borehole is not angled so that the sensor can be
installed precisely at a later stage.
Attention!
•After drilling it is essential to check whether the drill bit has caused
any burr on the borehole edges. Any burr on the pipe must be
removed using a suitable tool. If the burr is not removed it may
affect the sensor‘s calibration.
•If the sensor will not installed immediately, the socket could be closed by an 1” end cap.
•The sensor is delivered with a probe length adapted to the pipe diameter.
•The sensor is then inserted through the sensor socket and fixed.
•The purge air connected via an M5-connection nipple.
The following condition must be fulfilled for the purge air:
•The purge air must be continuous, no pulses.
•The pressure should be minimum 0.5 bar over the pressure in the transmission pipeline.
•In principle, the pressure strength should be selected in such a way that no material can deposit
between the sensor rod and the inner wall of the nozzle.
•The flushing air must be dry, free of oil and environmental conditions.

4.4 Mounting the Evaluation unit
The evaluation unit can be installed at a maximum distance of 300 m from the sensor. A cable of type “Ölflex
Classic 110 CY” is recommended. The cable should be four wired, twisted and shielded. A minimum cable
cross-section of 0.75 mm² should be observed. For distances more than 150 m the cable cross-section
should be adjusted.
The housing is prepared for DIN Rail mounting according to DIN EN 60715 TH35.
