Oval PG30D Instruction Manual

NONCONTACT PULSE GENERATORS
MODEL PG30D
■ GENERAL
When used in conjunction with an OVAL flowmeter, the Model PG0D/PG0DEP noncontact pulse
generator provides voltage frequency pulses proportional to the flowrate of process fluid. The pulse
generator contains a pulse generating element of molded type and a protective circuit which prevents
erratic pulses otherwise generated by minute vibration of generator components. As the slit disc revolves,
a succession of voltage pulses (rectangular wave) is generated which can be used in a remote totalizing,
batching or blending system built around an OVAL flowmeter as the front end of signal pickup.
The pulse generator also offers compatibility: for example, PG0D may be replaced by PG0EP, PG0,
or PG0EP, while PG0DEP with PG0, PG0, or PG0EP.
By construction, this pulse generator comes in two types: PG0D (standard) and PG0DEP (flameproof).
■ TYPICAL PULSE GENERATOR INSTALLATIONS
Engineering-unit pulse generation ... The rotor revolution is, after gear reduction and instrumental error
correction for the flowmeter, picked up and used primarily for remote totalization.
