This pulse generator is designed to mount on an OVAL flowmeter or UF-II flowmeter and generates a frequency voltage pulse or current pulse signal proportional to the rate of flow. The signal generating element is entirely molded and contains a circuit to prevent stray pulse generation otherwise caused by vibation, thus making this pulse generator a highly reliable instrument. It comes in three designs, Models PG30EP, PG30SEP and PG30DEP. These are classified in the general specification on the next page. The flameproof configuration is designed and fabricated in accordance with the “Explosionproof Guidelines” recommended by established standards.
