The voltage at the minimum linear flow is greater than 30 millivolts peak to peak when measured into a 10 000 ohm load On larger size flowmeters the output level may exceed several volts peak to peak The DC output resistance of the magnetic pickup coil is generally less than 2 000 ohms Detailed impedance characteristics are available on request MODULATED CARRIER PICKUP MCP TYPICAL RANGE 100 1 The Hoffer MCP pickup is an active coil which eliminates pickup drag and requires a Modulated Carrier Signal Conditioner be mounted on or near 10 feet or less the flowmeter The MCP works on a principle where the motion of the rotor modulates a high frequency signal The conditioner demodulates filters amplifies and shapes the resulting signal prior to transmitting it as a high level signal Use of the MCP pickup allows for wider flow ranges than can be achieved with low drag magnetic pickups The cost compares with that of a preamplifier for a magnetic pickup This pickup type is used extensively when a wide flow range is required or with flowmeters that are being used with a universal viscosity calibration curve UVC Typically MCP coils can obtain flowmeter ranges of up to 100 1 QUADRATURE OUTPUT OPTION When a Hoffer Turbine Flowmeter is equipped with two pickup coils properly positioned on the flowmeter housing it is possible to sense flow direction flowrate and total flow as well as add subtract options The pickup coils gen
