KDLD Battery Powered Converter- milk flowmeter


It is designed for electromagnetic flow meters that are used in the open field, the 3.6V battery has a service life of more than 5 years. With SRD, GPRS and CDMA remote signal transmission, you can get the info without being on site. Applicable size: DN10~600


Selection of Nominal Diameter- milk flowmeter

1.As electromagnetic flowmeter has a high rangeability of 1500:1, the selection of nominal diameter is the same as that of process pipe;


2.If there are solid particle in the measured medium, a flow rate range of 1~3m/s is recommended. If the practical flow rate is excessive yet inconvenient to adjust, the nominal diameter of the instrument is better larger than that of the process pipe, under which condition the flow rate in the measuring pipe of the flowmeter can be properly decreased and the abrasion of electrode and liner caused by the particle can be alleviated;


3.If there are sediment in the process pipe, a flow rate range of 1~3m/s is recommended. If the practical flow rate is too little, the nominal diameter of the instrument is better smaller than that of the process pipe in order to properly increase the flow rate of the fluid in the flowmeter to avoid the effect on the accuracy caused by the sediment.


4.If the flow rate is too little yet a high-precision measurement is required, a sensor smaller than the nominal diameter can increase the flow rate to ensure high precision.


In the above 2,3,4 conditions, a reducing pipe should be jointed to both the upstream and downstream of the flowmeter. The center taper angle should be no more than 150 and there should be a straight pipe at least 5 times of the the process pipe jointed to the reducing pipe.


To help making lectotype, several flow values which corresponding to the certain typical flow rate are listed in the table below, any flow value could be quickly work out based on the corresponding flow rate: If a flow value is known as Q(m3/h), according to the relevant nominal diameter, check out the corresponding flow value Qwith a flow rate of 1m/s, then the flow rate can be work out through a formula as V=Q/Q1(m/s).
