Positioning

The PE202 can be mounted vertically or horizontally. It is 

important to choose a position that will ensure full pipe.  

(Under certain conditions of empty or partially-full pipe 

the  meter  may  give  a  pulse  out  when  there  is  no  flow.) 

With a zero straight pipe requirement after an elbow, the 

PE meter can be installed in tight spaces.

Mounting

It is highly recommended to use the mounting bracket 

provided. The mounting bracket uses two #8 screws on a 

1.5” center. 

The PE202 may be supported by its piping connections 

IF

 

the piping is rigid. The meter and pipe must be perfectly 

aligned with no flexion at the fittings to prevent leakage or 

damage to the meter.

INSTALLATION

Piping

Metal pipe, metal tube, or plastic tubing can be used with 

the meter.  The standard NPT fittings can be used with or 

without NPT adapters on 3/4” or 3/8” pipe. If used, apply 

Teflon tape onto the NPT fittings. NPT adapters should be 

hand  tightened  onto  the  fittings.  Thoroughly  clean  the 

pipe  threads  and  nose  and  apply  Teflon  tape  to  adapter 

threads. Hold adapters with a wrench while tightening the 

pipe to prevent damage to the meter. 

Power Supply

A 12 Vdc linear, regulated power supply with an output 

current of at least 0.25A is recommended. If a switching 

power supply must be used, consult Seametrics for 

approved manufacturer’s model numbers.

Grounding

In addition, it is necessary for proper operation to ground 

the unit to a good quality earth ground. Assure negative 

power supply is grounded to earth and to the entire 

electrical/mechanical system.  If metal piping is used, 

jumper inlet and outlet pipes together and connect to 

ground for best results in metering accuracy.  The cable 

shield drain wire should be left unconnected.
