The BilgMon 488 For Marine 15 PPM Bilge Alarm is approved and certified in accordance with the latest IMO resolution MEPC.107(49) and in addition, designed to meet the particular needs from the crew when processing the bilge water.
Brannstrom Sweden AB was founded in 1985 by the present owner Roland Brännström as a company specializing in developing tailor-made systems for, and in close co-operation with, the customers.
In the beginning, the focus was set on design, development and production of specific types of measuring processors for the marine market – ‘bilge alarms’, but also PC-Board design, and development of control systems and turbidity meters for sewage treatment plants. The company expanded, and the product range of today involves systems within areas reaching from marine pollution control systems (ODMCS) to land based paper mill in-line monitoring systems.
The company is normally handling all involved activities that are included in the development of new systems, such as layout work, detail design, software development, production of PCB boards, computer assembly, and a final inspection and test of every unit, before delivery.
All systems are designed for heavy-duty work, in tough environment conditions, in compliance with certification and test conditions established by international regulatory bodies such as IMO and Classification Societies, as well as National Administrations.
15 ppm Bilge Alarm – General
The IMO Res. MEPC.107(49) resolution regulates the design and performance of the oily water separators and the 15 ppm Bilge Alarms for machinery space bilges of ships. Each ship must have a certified 15 ppm bilge alarm for measuring the oil content in the discharge water. The 15 ppm Bilge Alarm shall give an alarm and initiate automatic stop of overboard discharge of oily mixtures, according to the latest requirements.
The Bilgmon 488 can be easily retrofitted onto any type or model of OWS instead of the current 15 ppm alarm monitor. The 15 ppm monitor Bilgmon is developed and manufactured in a very compact and simplified function so it fits all applications and models/brands from other manufacturers.
The Bilgmon 488 comes in both 24V and 115/230V versions so when doing the retrofit you simply have to fit in the new piping and connections, all of which can be done without any hot work.
In case the automatic stopping device consists of a solenoid valve draining a lot of current, you have to consider that the relay contacts of the Bilgmon 488 are fitted with electronic fuses rated at 0,25A. In case 0,25A is not sufficient, you might have to install an external relay between the Bilgmon 488 alarm relay output and the ASD
Main Features
• Unique system of onboard replacement of the measuring cell.
• Measuring cell simple to replace due to wireless design.
• Easy to operate with 4 only pushbuttons.
• Userfriendly menu.
• Compact design.
• 32 character LCD, with LED background light.
• Relays and input are protected by “PTC” resistor fuses. Fuses are
reset by disconnection of power supply – no regular fuses to replace.
• System running status shown on LCD in real time.
• Suitable for both newbuildings, as well as existing ships.
• Can be attached to any oily water separator type.
BilgMon 488
The BilgMon 488 has a unique system of replacing the old measuring cell with a new one, and still keep all data saved in the memory. This function enables the crew to easily replace a damaged measuring cell, or attach a new calibrated measuring cell to the power module, when a calibration of the unit is needed.The replacement cell is delivered with a factory calibration certificate, and both units will be automatically updated after being joined together. The measuring cell has a heavy duty design, in order to resist the tough running conditions.
The measuring principle by using IR light detection in the measuring cell, is a well proven and reliable examination method of the sample flow from the oily water separator.
The processor in the power module will store all requested data, and this data will clearly be presented in a LCD at the front of the unit. Connection to an external printer is available if required, through a serial communication interface. The unit is also provided with a solenoid valve function for cleaning water to measuring cell.
Approvals
The BilgMon 488 is type approved by the Marine Administration as specified in the IMO regulations. In addition to this, the system is type approved by several classicifaction societies. It has also the “MED”- Marine Directive approval, for equipment to be installed onboard ships, in accordance with the European Council Directive 96/98/EC.
