Microwave detector for contactless monitoring
of material flows for "flow" or "no flow"
Absolutely insensitive against material deposits
For any line diameter
With adapter, usable up to 220 °C and 20 bar
With ceramic mounting, usable up to 1,000 °C
Compact (no separate electronics)
Signalling through relay switching
Different sensitivity levels
Detection through all non-conductive walls
Can also be supplied with short housing and separate electronics
Detection of material clogging and material standstill
The FlowJam detects solid flows of all types for material movement.
A differentiation is made between the following switching states:
- Material flow
- Material clogging / standstill or empty pipe
The system operates with no contact, using microwaves in a process in which the material movement is detected by using the Doppler effect.
The FlowJam is an especially process-secure device, since the microwave can penetrate material coating on the sensor and reliably detect the material movement behind it. If container walls, housings or pipelines are not metal, it is possible to measure from the outside.
The FlowJam can also be used under difficult conditions such as high operating temperatures and pressures with the help of a process adapter.
The FlowJam can be easily installed in the following ways:

WARNING
Only tighten valve positioner with your hand! Do not use any tools
when tightening as otherwise the thread may be damaged.
6 Using the product
6.1. Preparing for measurement
6.1.1. Connecting the temperature sensor
Sensors must be connected before the measuring
instrument is switched on, so that they are recognised by
the instrument.
Surface temperature sensor
An NTC temperature sensor (accessory) must be connected for
measuring the pipe temperature and for automatic calculation of
superheating and subcooling.
Deactivating the surface compensation factor for insertion and
air temperature sensor
A surface compensation factor has been set in the measuring
instrument to reduce the measuring errors in the main field of
applications. This reduces measuring errors when using surface
temperature sensors.
If the measuring instrument testo 550 is used in combination with
insertion or air temperature sensors (accessories), this factor must
be deactivated:
> Press and hold the keys SET + MODE together and switch on
the measuring instrument [ ].
- The instrument shows the message Fact off.
The surface compensation factor becomes active every
time the measuring instrument is switched on.

6.1.2. Switching the instrument on
> Press [ ].
Zeroing the pressure sensors
Zero the pressure sensors before every measurement.
✓ All connections must be pressureless (ambient pressure).
> Press key [P=0] and execute zeroing.
Connecting the refrigerant hoses
Before each measurement check whether the refrigerant
hoses are in flawless condition.
✓ The valve actuators are closed.
1. Connect the refrigerant hoses for low-pressure side (blue) and
high-pressure side (red) to the measuring instrument.
2. Connect the refrigerant hoses to the system.
WARNING
The measuring instrument dropping down or any other comparable
mechanical load can cause breakage of the pipe pieces in the
refrigerant hoses. The valve actuators may also suffer damage,
which in turn could result in further damage inside the measuring
instrument, which may not be detectable from outside.
> For your own safety you should return the measuring
instrument to the Testo Service for technical inspection.
> You should therefore always replace the refrigerant hoses with
new ones after the measuring instrument has dropped down or
after any comparable mechanical loading.

6.2. Performing the measurement
WARNING
Risk of injury caused by refrigerant that is at high pressure,
hot, cold, or poisonous!
> Wear safety goggles and protective gloves.
> Before pressurizing the measuring instrument: Always fasten
the measuring instrument at the suspension device in order to
prevent it from falling (risk of breakage)
> Check if the refrigerant hoses are intact and connected
correctly before each measurement. Do not use a tool to
connect the hoses. Only tighten the hoses by hand (max.
torque 5.0 Nm/3.7 ft*lb).
> Maintain permissible measuring range (0 to 50 bar). Pay
particular attention with systems with refrigerant R744, as
these are often operated with higher pressures.
Measuring
✓ The steps described in the chapter "Preparing for
measurement" have been completed.
1. Pressurize the measuring instrument.
2. Read off readings.
With zeotropic refrigerants, the evaporation temperature
to/Ev is displayed after the complete evaporation/the
condensation temperature tc/Co is displayed after the
complete condensation.
The measured temperature must be assigned to the
superheating or the subcooling side (toh <--> tcu).
Depending on this assignment, toh/T1 or Δtoh/SH or
tcu/T2 or Δtcu/SC is shown depending on the selected
display.

Tightness test/pressure drop test
Systems can be tested for tightness with the
temperature-compensated tightness test. The system
pressure and the ambient temperature are measured
over a defined period for this. A temperature probe can
be connected that measures the ambient temperature
for this (recommendation: NTC air probe, art. no. 0613
1712). Information about the temperature-compensated
differential pressure and about the temperature at the
beginning/end of the test exists as a result. If no
temperature probe is connected, the tightness test can
be performed without temperature compensation.
