SU Series

Power Supply Unit:

SU1503

The power supply unit furnishes required DC power to the signal generator, converter, etc. of flowmeters.

Pulse Distributor:

SU1508

This instrument receives a pulse signal from a flowmeter, etc., shapes it, and provides three isolated pulse signal outputs.

Frequency - Current/Voltage Converter (F/I Converter):

SU1512

This instrument receives a pulse signal from a flowmeter, etc., shapes it and, after isolation, changes it into analog signals.

Pulse Scaler:

SU1513

This instrument receives a pulse signal from a flowmeter, etc., shapes it and, after isolation and scaling, furnishes two sets of pulse outputs with a desired frequency division and pulse width.

Meter Selector:

SU1352

Using two flowmeters, large and small in capacity, this instrument can expand the flow range within the range of standard accuracy.


Other Electronics

USB Connection
Smart Communication Unit:

EL2310

The Smart Communication Unit is a communication terminal unit that enables the operator to set up, alter, adjust parameters, or read out variables in the field or remotely through interactive communications when used in combination with OVAL Smart series flowmeter (ULTRA OVAL, CORIOLIS, DELTA).

Pulse Checker:

PC2201

This instrument is a versatile electronic maintenance tool having the functions of totalizing pulses required for adjusting various kinds of measuring instruments, measuring and generating frequencies, and providing batch pulse output. Basic inspection and adjustment of flowmeters, converters, receiving instruments, computing instruments, etc. manufactured by OVAL can be done by using this instrument.
