Dynamometer / Well Sounder Mechanical Dynamometer DYN 77 Electronic Dynamometer DYC Acoustic Well Sounder AWS Electronic Well Sounder EWS Electronic Dyco Sounder EDS Permanent Dynamometer PDM Theta Rod Pump Software	Dynamometer DYN 77 for deep well pump analyses. Diagrams can be recorded during the pumping cycle, without the need to stop the pump or to change the plunger setting-depth. Electronic Dynamometer DYC for deep well pump analyses. Diagrams can be recorded during the pumping cycle, without the need to stop the pump or to change the plunger setting-depth. The Acoustic Well Sounder AWS is a precision instrument for determination of the fluid level in the casing of a pumping well. The Electronic Well Sounder EWS is a precision instrument for determination of the fluid level in the casing of a pumping well. This computer-supported fluid level recorder makes it easy to find, calculate, and print accurate fluid level data. The Electronic Dyco Sounder EDScompact is a combined unit of the Electronic Dynamometer DYC and the Electronic Well Sounder EWS. The Leutert Permanent Dynamometer PDM is a microcontroller aided fixed installation data acquisition unit. It is especially designed to monitor and analyze rod pumping systems. Leutert´s electronic dynamometers combined with Theta´s diagnostic software offer a complementary system to optimize your rod pumps´ efficiency.
