The ADS PrimeProbe®2 is a bi-directional insertion flowmeter for use in managing water 
distribution systems. It has no moving parts making it reliable and ideal for use over a wide range 
of flows. PrimeProbe2 is suitable for use in pipe sizes from 4” to 48” (larger sizes available upon 
request).

Precautions and Switch-on of the ADS PrimeProbe2 
Safety and Precautions 
Please read these instructions carefully as they contain important safety information.  PrimeProbe2 
must be used for the specified application - improper use or tampering will invalidate the warranty. 
ADS is responsible only if used in original product configuration.
The PrimeProbe2 should be installed away from any bends or hydraulic fittings. For best results, •	
it should be installed with at least 25 pipe diameters of straight unrestricted pipe upstream of the 
sensor, and 10 pipe diameter downstream of the sensor.  
For correct operation, the pipe must be completely full of water.  It is not necessary that the •	
probe be installed vertically. But must be installed at 90° to the pipe.
Before inserting the probe, ensure the safety chain is correctly secured at both ends•	.  Pipes are 
under pressure - failure to tighten the locking collar and connect the safety chain could cause the 
probe to be forced upwards with potential injury to the user.
Important•	 – Fully tighten all screws as water ingress can occur.

Installation Do’s and Don’ts
Vertical installations are preferable in ascendingflow
For vertical installationswith descending flowdirection, contact ADS
Avoid installation near curves or hydraulicaccessories
The opening of the ball valve before tightening the fixing side screws could cause the expulsion of the sensor from the pipeline
Avoid the functioning with the pipe partially empty
WARNING!!!WARNING!!!
During the functioning, the pipe must be completely full of liquid, or completely empty
Install the sensor away from curves and hydraulic          accessories
Before opening the ball valve, fix the sensor with two side screws 
						

							Flow Direction
Before completion of installation, confirm the direction of the flow of liquid in the pipe.  Using 
the nameplate as a reference, flow direction is positive when the flow direction is from – to +. 
If the flow direction is reversed after installation, it is sufficient to reverse the sign of the KA 
Factor (refer to operating manual “Programming the Converter”). However, it is preferable to 
reverse the probe by rotating through 180 degrees.
Grounding the Probe
For accurate results, it is necessary that the probe and the liquid are both 
at the same potential.  To achieve this always connect the sensor to the 
earth.  On pipes with cathodic protection, please contact ADS for advice.
IMPORTANT NOTE:
Fluctuating flow-rates are usually an indication of a poor earth connection, excessive vibration or electrical 
noise on the pipe.
Switch-on and Off
When installation is complete the PrimeProbe2 must be switched ON to take it out of Sleep Mode, as described below.  See 
Operating Manual for further details.
1) Launch the PrimeWorks software.  Connect the PrimeProbe2 to the software using the communications cable. In PrimeWorks 
select the PrimeProbe2 - Wake up menu option.  The software will initiate communications with the PrimeProbe2 to bring it out of 
Sleep mode.  The probe is now ready for use. 
2) Upon completion of usage it is recommended that the probe is returned to Sleep Mode by selecting Primeprobe2 - Sleep in 
PrimeWorks.
