Lectotype Instructions

The measured fluid must be conducting liquid or slurry with a conductibility no less

than 5μs/cm, avoid fluid with too much ferromagnetic substance or bubble. The pressure

rating, liner material, electrode material and instrument structure should be chosen based

on the characteristics of the fluid.

Selection of nominal diameter

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 centre 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

14

the relevant nominal diameter, check out the corresponding flow value Q1 with a flow rate

of 1m/s, then the flow rate can be work out through a formula as V=Q/Q1(m/s).

regia and ammonium salt.

As there is a great variety of medium and their corrosivity can be affected by

complexity factors such as temperature, concentration, flow rate, etc., the above two

tables are just for reference. Customers should make choices according to the practical

situations, if necessary, corrosion resistance experiment like hanging sheet experiment of

simulation materials should be performed.

Grounding flange

Applicable to non-conductive pipeline like plastic

pipeline. However, it is not required for the sensor

with polytetrafluoroethylene liner.

Inlet protection flange

Applied when the medium has strong wear ability,

often used with polyurethane liner. However, it is not

applicable to the sensor with polytetrafluoroethylene

liner.

Ordering notes

Please read this brochure carefully to know the product model and coding

rules before ordering, then choose the right product(s) and relevant code

according to practical requirement. For remote flowmeter, a special cable of 10

meters is provided along. If the spacing is greater than 10 meters, guests
