Flow MetersFlow Meters is a device used to measure fluid flow through a pipe, in which Flow Rate can be Volumetric or Mass. Volumetric Flow Rates are resent by units of liter/minute, liter/hour, m3/minute, m3/hour, etc. Mass Flow Rate represents kg/minute, kg/hour, ton/minute, ton/hour, etc. Choosing the right Flow Meters is always a Challenge.

Input Types: NO or NC switches: No external excitation required. Open collector transistor: Open circuit voltage approx. 3.3 VDC. Logic Levels: LOW = 0 to 0.9 VDC, HIGH = 2.4 to 28 VDC Update Rate: 41 ms following alarm state; 1 ms for alarm state clear. Sequences: Input follower, ISA Sequences A, F1A, F2A, F3A, M, F1M, and F3M per ISA Standard ISA-18.1-1979 R2004. Sequence Options: A, F1A, F2A, F3A, M, F1M, F2M, and input follower with selectable options -1 (silence pushbutton), -4 (no lock-in), and -6 (no horn) per ISA Standard ISA-18.1-1979 R2004
Rating: 2 SPDT (Form C); rated 3 A @ 30 VDC or 3A @ 250 VAC resistive load; 1/14 HP @ 125/250 VAC for inductive loads. Electrical Noise Suppression: A suppressor (snubber) should be connected to each relay contact switching inductive loads to prevent disruption to the microprocessor’s operation. Recommended suppressor value: 0.01 µF/470 Ω, 250 VAC (PDX6901). Relay Operation: Relay 1: Alarm state until the alarm is acknowledged. Relay 2: Alarm state if any channel indicating an alarm condition. Fail-Safe Operation: Programmable independent for each relay. Note: In fail-safe mode, the relay coil is energized in non-alarm condition. In case of power failure, the relay will go to the alarm state.

First-Out Alarm Indication
The Vigilante II can be programmed for multiple sequences with first-out alarm indication. This feature indicates the first point of failure of a system when multiple alarms occur.
Multiple Unit First-Out Alarm Indication
If multiple Vigilante II annunciators are connected for multiple unit first-out indications, only one input from all connected devices will display as a first-out alarm.
