MacBAT 5 – USER GUIDE. Version 1.0
PRESSURE AND TEMPERATURE MEASUREMENT
Primary pressure sensor P1
Sensor types:
• Internal – thread available on the right side of housing
• External – sensor installed on the cable, length up to 10 meters
Thread:
• Metric thread M12x1,5
• Inch thread 1/4NPT on demand
Ranges of the sensors [bar A (absolute)]:
• 0,8-6 / 0,8-10 / 2-10 / 4-20 /7-35 / 4-70 / 10-70 / 10-100 / 20-100
Secondary pressure sensor P2
Sensors types and threads equal to P1
Ranges of the sensors [bar G (gauge)]:
0-0,1 / 0-0,3 / 0-1 / 0-6 / 0-10 / 4-20 / 7-35 / 10-70 / 10-100 / 5-55
Temperature sensor Pt1000 class A in two variants:
• 50mm length, 5,7mm diameter of the casing – insertion into the gas meter socket
• 140-180mm adjusted length, 6mm diameter of the casing – insertion into the welded
thermowell in the gas pipe

Periodic registration: configurable period from 1 to 60 minutes. Memory horizon: 36000 records (over 4 years @
60 min period)
Measurement cycle: every 6-60 seconds when supplied from battery; every 1-60 seconds when supplied from
INT-S3
Hourly data: 11500 records (over 16 months);
Daily data: 1400 records (about 4 years)
Monthly data: about 450 records
Periodic data 2 (configurable period, by default at 10th, 20th, last gas day of month): about 800 records
Two separate events memory sectors:
• Alarm LOG list: high prominence values related to measurement – pressure range exceeding, flowrate
exceeding. Alarms requiring constant review and acknowledgement. Filling the memory more than 95%
will cause device counting to error counters. Capacity: about 3000 records.
• Event LOG list: events appearing during normal device operation – digital inputs state change, enclosure
opening, power supply connected. Memory sector is overwriting – oldest events are erased when new are
appearing. Memory capacity – around 2000 records. Capacity: about 3000 records.
