Accuracy 2-60s for optional Response time Flow Velocity Range 0.05- 12 m/s Liquid Types Supported Liquids containing 100ppm of reflectors and at least 20% of the reflectors are larger than 100 micron.
Doppler Ultrasonic Flowmeter DF6100-EP Manual PART 2 PORTABLE TRANSMITTER 2.1 TRANSMITTER Fig 2.1 Portable flow meter One standard set of product includes: Soft case, portable transmitter, standard transducers, couplant, stainless steel belt, charger, 4-20mA output cable terminals, etc. The flow meter is equipped with a rechargeable lithium battery. This battery will require charging before initial operation.
Doppler Ultrasonic Flowmeter DF6100-EP Manual • If the portable flow meter is stored for prolonged periods of time, had better store at a temperature below 21ºC. • Try to avoid the meter working while battery charging. 2.2 OUTPUT INTERFACES Brown:4-20mA Red:4-20mA...
Doppler Ultrasonic Flowmeter DF6100-EP Manual 2.2.2 Relay output (If portable flow meter needs this functionality, please make a statement when placing orders) Please refer to 4.3.14 Dual Relay Configuration to see Menu Configuration. The relay operations are user configured via the front panel to act in flow rate alarm or error alarm, power supply interruption alarm and totalizer pulse.
Doppler Ultrasonic Flowmeter DF6100-EP Manual PART 3 CLAMP-ON TRANSDUCER INSTALLATION 3.1 TRANSDUCER MOUNTING LOCATION Placement of the ultrasonic transducer is the most critical step in achieving an accurate and reliable flow reading. All flow meters of this type rely on a full-pipe of fluid that is flowing symmetrically (evenly) in the pipe.
Doppler Ultrasonic Flowmeter DF6100-EP Manual 3.2 TRANSDUCER INSTALLATION PROCEDURES Locate the reference mounting positions of 3 and 9 o’clock (180° symmetrically) as shown in Fig 3.1. Fig 3.1 Two transducers must be installed 180° symmetrically. Two transducers called A and B transducer, A is transmitting transducer and B is receiving transducer, they must be installed 180°...
Doppler Ultrasonic Flowmeter DF6100-EP Manual Mounting of high temperature transducers is similar to Doppler flow meter standard transducers. High temperature installations require acoustic couplant Dow Corning 112 that is rated not to flow at the temperature that will be present on the pipe surface.
Doppler Ultrasonic Flowmeter DF6100-EP Manual PART 4 INSTRUMENT PROGRAMMING 4.1 GENERAL The Doppler flow meter contains a four-key tactile feedback keypad interface that allows the user to view and change configuration parameters used by the Doppler flow meter operating system.

Doppler Ultrasonic Flowmeter DF6100-EP Manual 4.3.10 Low Flow Cut-off FL C-OFF – Low Flow Cut-off A Low Flow Cut-off entry is provided to allow very low flow rates (that can be present when pumps are off and valves are closed) to be displayed as Zero flow.
Doppler Ultrasonic Flowmeter DF6100-EP Manual CAL 4MA CAL 20MA 4-20 TEST 4-20mA Span The FLOW 4MA and FLOW 20MA entries are used to set the span of the 4-20mA analog output. These entries are volumetric rate units that are equal to the volumetric units configured as Engineering Rate Units and Engineering Units Rate Interval.
Doppler Ultrasonic Flowmeter DF6100-EP Manual FLOWALM is corresponding to Wiring terminal “RELAY -, +”, only can be user configured as flow rate alarm, error alarm, or power supply interruption alarm output. Flow Rate Relay configuration permits relay changeover at two separate flow rates allowing operation with an adjustable switch deadband.
