Macnaught Hazard Area Flow Meter Portfolio
Flame Proof (ExD) Flow Meter
Macnaught's ExD C1D1 flow meter is built off the legendary MX flow meter assembled to a ExD Flameproof Class 1 Division 1 sensor approved with all major certifications FM-US, FM-CA, ATEX and IECEx.
- Flow Ranges from 0.13 GPH to 600+ GPM in sizes 1/4" thru 4"
- Pulse output is NPN type
- Temperature ranges from -56°F to 284°F
- 0.5% volumetric accuracy with 0.03% repeatability
- ExD Meters, displays and flow computers in stock
- 3 meter cable
- Large stock of ExD displays on hand
Intrinsically Safe (Ex ia) Flow Meter
Macnaught's Ex ia Intrinsically Safe flow meter meets all major C1D1 approvals and certifications and supersede C1D2 requirements with FM-US, FM-CA, ATEX and IECEx.
- Flow ranges from 0.13 GPH to 600+ GPM in sizes 1/4" thru 4"
- Stocked output is a proximity sensor with Namur connection and 15-meter cable
- Temperature range -13°F to 158°F
- Optional omni polar NPN sensor available
- Safety barrier provided by others. Entity parameters to size barrier:
- Ui = 20v li= 60mA Pi = 200mW Ci = 150nF Li = 150uH
- I.S Displays in stock
Simple Safe (Ex ia) Flow Meter
Macnaught's latest hazard offering allows for non-powered hazard meter application. Perfect for remote locations or areas where power is not available. The MX Meter is mated with Macnaught's Simple Apparatus PCB and meets all global intrinsically safe areas.
- PCB is completely passive and adds no energy to connected circuits.
- Rate and total only option are completely non-powered.
- Batch and output versions require power, and a safety barrier (provided by others) see instructions for entity parameters.
- Temperature ranges: -40°F to 158°F
- Rate and total are standard display, batch and relay options available.
