PRODUCT PARAMETERS for intelligent open channel flowmeter
LDM-51 Open Channel Electromagnetic Flow Meter
I. Product function introduction
LDM-51 open channel electromagnetic flow meter is a flow automatic measuring instrument use
for continuous measurement in open pipeline(half pipe sewage or mass flow pipe with none down
flow weir) by velocity-area method. It can measure and display instantaneous
flow rate, flow
velocity, accumulated flow rate and any other data. It’s specially applicable to the measurement of
municipal rainwater,sewage water,waste water and irrigation water.
The LDM-51 open channel electromagnetic flow meter is composed by a electromagnetic velocity
sensor, a water level sensor and a flow display. It continuous measure the flow rate and liquid level
of the liquid in the pipe. The user only input the circular pipe diameter or width of the square pipes,
LDM-51 open channel electromagnetic flow meter will automatically calculate and display the
flow, instantaneous flow rate, flow velocity, accumulated flow rate and etc. measure parameters.
1.1 Basic function
(a)Low-frequency square-wave exciting, exciting frequency: 1/16 power frequency;
(b)Exciting current can be selected for 50mA, 75Ma, 100mA;
(c)Current speed range: 0.01 --- 10m/s,current speed resolution: 1mm/s;
(d)DC 3.6V switching power,range of voltage: 3.6VDC;
(e)DC 12V switching power,range of voltage:12VDC --- 30VDC;
(f)Network function:MODBUS(RTU), TTLLEV 3.6VDC power;
(g)English displaying mode(other languages can be set);
(h)Forward and reverse measurement could be customized, and record: Forward gross, reverse
gross, show 10-digits;
(i)Used for open channels(circular, Rectangular, and special channels);
(j)Used for continuous measurement of municipal rainwater, sewage water, waste water and
irrigation water;
(k)Both forward and reverse flow measurement;
(l)Sensors can be in bad live and waste water quality under long-term reliable operation;
(m)The velocity measurement range: 0.05 --- 10 m/s;
(n)High measurement precision and it is not affected by the downstream tributary of harmony to
the factors of water blocking;
(o)Short measuring pipe straight pipe requirements;
(p)Big screen back light liquid crystal display, whether bright light or night to be able to clearly
read measurement data;
(q)Instrument display and output the function is available, it can display instantaneous flow
velocity of cumulative flow data, and communication interface with the computer RS485
(optional);
(r)GSM and GPRS wireless data remote transmission function (optional);
(s)Nominal diameter circular pipes: DN100 --- DN6000(ultrasonic level meter: depth DN<h; range
> 5cm; stress level meter 2DN<h; range>2cm. DN is diameter size)
(t)Rectangular pipe: width ≤6m, depth ≤32m.
1.2 Special function
Remember the historical data forever, zero point adjust automatically. It could connected with
current meter(4-20A signal)
