Totalizing, Batching, and Monitoring Electronics Model ZOK

Description

The ZOK is designed to calculate, display, and transfer
calculations and flow rates of flow meters with pulse or
frequency outputs. It displays flow rate, a resettable day
count, and a total count. An easy to use menu guides
you through the programming. All program settings are
retained, even during a battery change. Option ZOK-ZxP
is offered in a panel housing with a protection of IP44. The
electronic option ZOK-ZxK is weather resistant and offers
IP66 / 67 ingress protection. The electronics are housed
in a UV-resistant, glass-filled plastic housing with stainless
steel screws and FKM seals. The ZOK-ZxF is available in a
powder coated aluminum extruded housing with a plastic lid
and offers IP 66/67 protection. They are all suitable for harsh
indoor or covered outdoor environments and complies with
EU Directive 2004/108/EC for electromagnetic compatibility.

Features:

● Self or External Powered, 8 Digit LCD Resettable and

Cumulative Totalizer, 5 Digit Rate Display as Main Value

● Rugged Field or Meter Mount Housing with Protective
Cover

● Easy to Program

● Accepts Universal Pulse Inputs

● Rugged IP 66/67 Universal Mount or DIN Panel Mount

● Long Battery Life

● Reverse Polarity Protection

● Optional Display Backlighting

● Preamplified Pulse

● Scalable Pulse Output

● Optional Wall or Pipe Mounting
