EX80-SERIES Insertion Electromagnetic Flow Meter

GENERAL INFORMATION

EX80-Series insertion electromagnetic flowmeters are designed for use with conductive liquids in 1 to 12” pipe. A choice of materials (stainless steel, brass, and PVC) allows the meter to adapt to a range of temperature, pressure, and corrosive environments.The EX80 insertion seametrics magmeter is highly suitable for difficult applications with changing viscosities and pulsating flows, such as air-driven diaphragm pumps. With no moving par ts, seametrics magnetic flow meters can be used in “dir ty” applications where debris would foul a mechanical meter. Like all magmeters, when used in chemical injection applications, these meters should be installed upstream of the chemical line (or far enough downstream to allow complete mixing of fluids before the meter).Designed for modularity and versatility, the EX80-Series seametrics measurement has a current-sinking pulse output that can be combined with the appropriate transmitter or indicator for the application

EX80-Series
	Fixed Depth Insertion Magmeter • Low-flow performance and accuracy superior to any mechanical flow sensor • No moving parts to wear out • Dedicated fittings for simple installation • Retainer clip automatically sets correct depth • Meter extends only ~1/8 of pipe diameter, minimizing potential for clogging with debris • Simple pulse train output can be used with any SeaMetrics signal processing module, or sent directly to a PLC • Available for pipe sizes 1" to 10", in Brass, 316 Stainless, PVC, and CPVC

FEATURES

• No moving par ts
• Economical
• Durable
• Easy to install
• Easy to maintain

APPLICATIONS
• Conductive fluids
• Small pipe applications (1”-12”)
• Industrial processes
• Chemical metering pumps
• Fer tigation





For analog output and display of rate and total, an FT420 can be used.  Blind analog output is provided by the AO55. The PD10 can be used to divide the pulse for pacing chemical metering pumps and the DL76 (data logger) is also compatible. Modules can be wall- or meter- mounted. If the EX80 meter is used with a programmable controller, the output signal can be fed direct, with no other conditioning required.EX80-Series fixed depth inser tion meters require special fittings. Factory installation in the fitting ensures correct depth placement in the pipe. The EX80-Series meter can be ordered in a full power model when a source of electricity is available, or in a low power model that can run on an external battery with solar panel. Reverse flow output and immersibility are optional.
