Insertion Electromagnetic Flow Meter

Description

Insertion Electromagnetic Flow Meter EX80 Series 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 EX81 is an insertion electromagnetic flowmeter for use with conductive liquids in pipe sizes 1” to 3”. The EX82 Insertion Magmeter is for use with pipe sizes 4” to 8”. With no moving parts, the insertion electromagnetic flowmeter is highly suitable for corrosive environments and for difficult applications such as those involving changing viscosities and pulsating flows. The insertion electromagnetic flowmeter is particularly recommended for metering the output of air-driven diaphragm pumps.

Fixed depth electromagnetic insertion flow meters

Designed for modularity and versatility, the EX80 series insertion electromagnetic flowmeters have a current-sinking pulse output, which can be combined with the appropriate transmitter or indicator depending on the application. For 4-20mA analogue output and display of rate and total, an FT420, pulse and 4-20mA output, can be used. For a 4-20mA analogue output only, the AO55 blind 4-20mA converter can be mounted directly onto the meter. If the EX80 series Insertion Magmeter is being used with a programmable controller, the output signal can be fed direct with no other conditioning required.

The EX80 series insertion electromagnetic flowmeters require a special fitting, since they are not depth-adjustable as are the EX100/200 series meters. Installation in the fitting ensures correct depth placement in the pipe. Fittings and sensors are available in PVC and stainless steel.

The EX80 is highly suitable for difficult applications with changing viscosities and pulsating flows, such as air-driven diaphragm pumps. With no moving parts, these flowmeters can be used in “dirty” applications where debris would foul a mechanical meter. Like all electromagnetic flow meters or 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 flow meters has a current-sinking pulse output that can be combined with the appropriate transmitter or indicator for the application. 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 flow meter is used with a programmable controller, the output signal can be fed direct, with no other conditioning required.

EX80-Series fixed depth insertion meters require special fittings. Factor y installation in the fitting ensures correct depth placement in the pipe. The EX80-Series flow 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 a solar panel.
