•   For Technical Assistance call +  215-674-1234

 

•   FAX: +  215-443-5117, 

•   E-mail: [email protected]

  

Please provide the following information:

•  Instrument Model and Serial Numbers

•  Sensing Element Model Number and Length

•  Material being measured

 •  Temperature

 •  Pressure

 •  Agitation

•  Brief description of the problem

•  Checkout procedures performed and results

Trained field service engineers are available on a time-plus-

expense basis to assist in start-ups, diagnosing difficult 

application problems, or in-plant training of personnel. Contact 

the service department for further details.
  

Periodically, AMETEK Drexelbrook instrument training seminars 

for customers are held at the factory. These sessions are guided 

by Drexelbrook engineers and specialists, and provide detailed 

information on all aspects of level measurement, including theory 

and practice of instrument operation. For more information 

about these valuable workshops, write to AMETEK Drexelbrook, 

attention: Communications/ Training Group, or call  215-

674-1234.

Any equipment being returned for evaluation or credit must be 

pre-approved by the factory.
In many applications, sensing elements are exposed to hazardous 

materials.

•   OSHA mandates that our employees be informed and 

protected from hazardous chemicals. 

•   Material Safety Data Sheets (MSDS) listing the 

hazardous materials to which the sensing element has 

been exposed MUST accompany any repair. 

•   It is your responsibility  to fully disclose all chemicals 

and decontaminate the sensing element.
