Pump Stroke Counters
The Two-pump Digital Stroke Rate Meter monitors and displays the Rate and Total Strokes of up to two individual pumps simultaneously. The unit continually displays, on large easy to read, low power LCD displays, RPM, TOTAL ACCUMULATED STROKES (0-9999 total strokes) and STROKE RATE (8-350 strokes per minute) for each pump. The unit is internally powered by a battery source having an operational life of 3 years.

The unit requires no calibration. It has a unique low-low voltage shutdown, preventing damage to the LCD displays due to extremely low operating voltages. The enclosure is waterproof, IP-66 rated and is of all stainless-steel construction. All labels are etched permanently into the enclosure. The entire package is designed to operate reliably in the harsh environment of high vibration, moisture and constant usage of both land and offshore drilling operations.
