Low cost ultrasonic flow meter can work alone without a LCD and Keypad module, the module can be used alone as a flow meter. Users can even integrate a number of the modules into a multi-channel flow meter that can measures up to several dozen of different pipes or a flow meter that has higher accuracy by measures the same pipe with all the channels. The design of the meter is intended to provide for users like system integrators and OEM users with a lowest cost but of high performance flow meter. Better than 1% accuracy. 0.2% of repeatability. Positive/negative/net flow or heat totaliser. MODBUS/MBUS/HIPEAK protocol. 4~20mA/PT100 platinum resistance input. OCT/RS-485/4~20mA output. Power supply by 24VDC for module, 85~264VAC/24VDC for display terminal.
Better than ±1% for velocity above 0.6ft/s
Better than 0.2%
Optional. LCD with backlight. 2×20 letters. Display instantaneous flow rate, accumulated flow rate (positive, negative and net rates), velocity, time, analog inputs, ect.
Current input: 4-20mA.,0.1% accuracy. Can be used for signals such as temperature, pressure, liquid level, ect.
Current output: 4-20m A . Impedance 0-1k, Accuracy 0.1% OCT output: two channels. Can be programmed as pulse signal for accumulated flow rate (positive, negative and net rates); frequency signal for instantaneous flow rate; ON/OFF signal for relay drive or alarm drive; batch control
RS-232 and RS-485 (note: can not be activated simultaneously)
Automatically record the following information: l The totalizer data of the last 64 days/64 months; l The time and corresponding flow rate of the last 64 times of power on and off events. Allow manual or automatic flow loss compensation l The instrument working status of the last 128 days
12VDC~24VDC Can be customized to 12VDC or 5VDC
Virtually all commonly used liquids (full pipe)
Liquid Suspension concentration
<20.000ppm, or ,<2%, particle size smaller than 100um.
All metals, most plastics, fiber glass, ect. Allow pipe liner
Straight Pipe Section
Longer than 15D, where D is pipe diameter. If a pump is near, the straight pipe section following the pump should be >30D
Shielded transducer cable. Standard length 5m (15’), Can be extended to (500m) 1640’. Contact the manufacturer for longer cable requirement. Cable should not be laid in parallel with high-voltage power line, neither should it be close to strong interference source such as power transformers
