Abstract
The invention discloses an inserted electromagnetic flowmeter and a mounting method. In the water supply of a pipe network, more and more flowmeters are used in large water user metering and region metering systems, and the leak rate is reduced. The inserted electromagnetic flowmeter can provide two-way high-accuracy measurement, and is an ideal flowmeter for leakage detection. The existing inserted electromagnetic flowmeter mostly consists of movable components, is short in service life, weak in antijamming capability, unreliable in measurement, high in manufacturing cost and complex in mounting. The inserted electromagnetic flowmeter comprises a mounting base (2), wherein the mounting base is connected with one end of a ball valve (4); the other end of the ball valve is connected with a flange (3); the connecting flange is connected with an end socket (5); the mounting base, the ball valve, the flange and the end socket are respectively connected with an electromagnetic flow sensor (6) which is connected with a junction box (7). The inserted electromagnetic flowmeter and the mounting method are used for measuring liquid flow.

described inserted electromagnet flow meter, it is inner that described electromagnetic flow transducer inserts described tested pipeline.
described inserted electromagnet flow meter, described ball valve is DN50 ball valve, described rubber seal, gland nut, collet threaded seat connect.
an installation method for inserted electromagnet flow meter, the method comprises the steps:
(1) welding slag and the burr of mounting seat on cleaning tested pipeline;
(2) turn off upstream flowrate by-pass valve control or adopt low pressure to supply water;
(3) ball valve is installed in described mounting seat, notes the vast sky chamber of described ball valve upwards;
check described ball valve whether can standard-sized sheet, complete shut-down, collet threaded seat, gland nut and rubber seal are installed on ball valve, unclamp setscrew nut, electromagnetic flow transducer insertion rod is inserted to described tested pipeline by described ball valve, should notice that described electromagnetic flow transducer Directional Sign bar sensing should be consistent with direction of flow simultaneously.
beneficial effect:
1. simple in structure, firm, the no-movable part of the present invention, long service life, measurement is reliable, antijamming capability is strong, volume is little, lightweight, easy for installation, maintenance is little, measurement range is large, measure the impact that not changed by temperature, density, pressure, viscosity, conductance etc., the pressure loss is zero.
