materials. It can be used with non-flammable, non-hazardous liquids 

up to 5 centipoise viscosity, but field calibration is recommended for 

accurate measurements.
It is important to note that most process water contains dissolved 

minerals. If the flowsensor is repeatedly exposed to process water and 

then the line is allowed to dry, these dissolved minerals will deposit 

onto the FP7002 and will inhibit the low flowrate operation of the 

sensor. If this occurs, cleaning of the sensor is recommended.

  

CAUTION

WATER HAMMER AND SURGES CAN BE DAMAGING TO 

ANY FLOWMETER AND MUST ALWAYS BE AVOIDED.
WATER HAMMER OCCURS WHEN A LIQUID FLOW IS 

SUDDENLY STOPPED AS WITH QUICK CLOSING AND 

SOLENOID OPERATED VALVES. SURGES OCCUR WHEN 

FLOW IS SUDDENLY BEGUN, AS WHEN A PUMP IS 

TURNED ON AT FULL POWER OR A VALVE IS QUICKLY 

OPENED.
LIQUID SURGES ARE PARTICULARLY DAMAGING TO 

FLOWMETERS IF THE PIPE IS ORIGINALLY EMPTY. TO 

AVOID DAMAGING SURGES, FLUID LINES SHOULD 

REMAIN FULL (IF POSSIBLE) AND PUMPS SHOULD 

BE BROUGHT UP TO POWER AND VALVES OPENED 

SLOWLY. IN ADDITION, TO AVOID BOTH WATER 

HAMMER AND SURGES, A SURGE CHAMBER SHOULD 

BE INSTALLED.

2.3 Flowmeter Installation

The FP7002 can be mounted in vertical or horizontal pipe runs; 

however, the pipe must be full of liquid for proper readings. Thus, the 

sensor should not be mounted in vertical pipe where the liquid flows 

down, since the pipe may not always be full in this situation. Refer to 

Figures 2-1 and 2-2.
