WELCOME TO EMCO CONTROLSWELCOME TO EMCO CONTROLSEMCO Controls is a Danish instrumentation company.The factory is placed in Hørsholm near Copenhagen, not far from Hamlet's Elsinore.From the premises in Hørsholm, domestic and export sales as well as manufacturing areconducted. We employ skilled people with many years of experience in manufacturing ofmechanical instruments.EMCO Controls originates back to 1966 and has right from the beginning been recognizedas a manufacturer of process control equipment including switches and indicators for levelmeasurement.ENGINEERINGDesign and engineering of our instruments are based on recognized international standards.Our work is supported by the latest version of Autodesk Inventor with 3 D solid modellingand computer programmes developed by our engineers.Our instruments are manufactured according to the EU Pressure Equipment Directive (PED)97/23 EC and CE marked when required by the process conditions.We continually strive to provide high quality sensors with design innovation to meet ourcustomers' requirements.MANUFACTURINGOur CNC machines for turning and milling are equipped with EDGECAM.QUALITY ASSURANCEA quality system according to ISO 9001-2000 has been implemented in order to manufactureaccording to a quality defined by international standards, by our customers and ourselves.CUSTOMER SEGMENTShipbuilding. • Power plants, incineration units, combustion units.General food industry. • Water treatment plants. • Pharmaceutical industry.Chemical industry. • General liquid handling industry.2WWW.PVL.CO.UK

CONSTRUCTION AND DESIGN OF INSTRUMENTS FOR FLOW, LEVEL AND TEMPERATUREQUALITY SENSORS WITHDESIGN INNOVATIONHISTORYEMCO liquid level switches have been manufactured since 1973 serving customers reliably inmany different industries including the shipbuilding industry.The present liquid level switch is developed by our engineers backed up by more than 30 yearsof know-how gained by close corporation with our valid customers.The initial stage of the new development was to set up the requirements to the design of thelevel switch. 5 major requirements were identified:1. Easy electrical and mechanical mounting2. Good corrosion resistance of the switch housing3. Modern design4. Low manufacturing costs5. High degree of flexibilityThe engineers within the company were able to solve 4 outof the 5 major requirements. The design of the level switchwas done by an industrial designer.ENGINEERING BASED ONINTERNATIONAL STANDARDSWWW.PVL.CO.UK3

LEVEL SWITCHAPPLICATIONThe EMCO level switch is designed to control the liquid level in vessels containing corrosive ornon-corrosive liquids.ALARM DUTYThe standard level switch with float code 01 is used for signalling high or low alarm points.The signal may be used for plant shut down or emergency override control.Level switch with float code 05 is intended for side mounting with alarm pointwith difficult accessibility.Level switch with float code 04 is for vertical mounting on top of the vessel. Level switcheswith long levers f. d. code 50 are used for alarm duty with unstable liquid surface or withinsulated vessels requiring long levers undisturbed movement.Liquid level interface, minimum difference in density 0,2PUMP/VALVE CONTROLTwo level switches with float code 01 are used for pump control where one switch starts thepump by activating a holding relay and the other switch brakes theholding relay when the desired liquid level has been reached.4WWW.PVL.CO.UK

CONSTRUCTION AND DESIGN OF INSTRUMENTS FOR FLOW, LEVEL AND TEMPERATUREFUNCTIONThe EMCO float switch can be mounted horizontally or vertically, but horizontal mounting isthe most common.The float lever carries a permanent magnet which is opposed by a similar magnet mounted inthe switch housing. The magnets having the same pole directed toward each other are separatedby a non magnetic diaphragm. The glandless construction offers excellent sealing.CONSTRUCTIONThe EMCO Float switch consists of 3 main parts :1. Housing with switch, electrical or pneumatic2. Mounting flange3. FloatThe modular construction of the EMCO float level switch offers excellent flexibility to suitcustomers' requirements.FEATURES• Easy to install • Very high flexibility • Fast delivery• Type approved by Det Norske Veritas, Lloyds Register of Shipping and Bureau VeritasApplicable for high temperaturesWWW.PVL.CO.UK5

MOUNTING FLANGEEMCO FLANGESEMCO flanges are delivered in 2 versions :1. The heavy duty flange (standard) with flange diameter of122 mm. with 4 Ø 13 mm bolt holes on a BCD of 92 mm.2. The light duty flange with flange diameter of 102 mm.with 4 Ø 7 mm. bolt holes on a BCD of 92 mm.The different types of counter flanges are shown on page 11A flat gasket for general use is available. The gasket is to be mounted between the level switchand the counter flange. For corrosive liquids special gaskets are available including PTFE and Viton.Mounting kit containing the gasket and 4 bolts is to be specified separately.STANDARD FLANGESFlange standards: DIN and ANSI/ASME others on requestFlange sizes:DN 65, DN 80, DN 100, 3”, 4”, others on requestFlange facing: Flat facing DIN 2526, tongue and groove DIN 2512,Flat face FF, raised face RF or ring type joint RTJ to ANSI B 16.5Pressure rating:PN 16, PN 40, PN 100, 150 lbs, 300lbs, 600 lbsFlange material: stainless steel AISI 316For reduced cost loose flanges in carbon steel are available as an option.BELLOWS SEALSEMCO and standard flanges are available with bellowsseals for applications where there is a risk that particlesin the liquid or viscous liquids will obstruct the freemovement of the float. The bellows is made ofNeoprene which reduces the operating temperature to 80° C.8WWW.PVL.CO.UK
