radial impeller heat meter

タイトルまたは説明

1、OUTLINE ACM series heat meters are new generation of central air conditioning / heating system energy measuring instruments, manufactured on basis of two patents of BASIC Company, combined with the situation of our country. It’s designed in accordance with Heat Meter Standard CJ*******0 and Heat Meter Verification Regulation JJG*******1. 2、Operating principle and application features of ACM Paten No.: ZL *2 2 ****9.8 Radial impeller type series flow sensor testing has three parts, transmitting circuit, receiving circuit, impeller module consisting of two pieces of ferrite ***** pulse signal will come into being when the impeller completes one rotation on its axis. The amplitude and period have no relationships with rotated frequency while the pulse frequency is more or less directly proportional to the flow-rate. The circuit has no torsional moment caused by magnetic reluctance component owing to the no magnetism design to keep a better linearity at the low flow-rate end. 3、Application note: There are a large quantity of impurities in the central air-conditioning and heating system circuits, as iron fillings, welding slags, etc. The normal flow sensor of rotor wing and woltmann type may cause a jam and wrap to the impeller easily, which results in a failure to the flow sensor. Basic radial impeller flow sensor with nonmagnetic design has low pressure loss and distinctive patent technology to prevent the flow sensor from suffering a jam or a tight chucking. Rigid alloy steel axle and artificial gem bearing make the product excellent wear resistance. The product fit bad water of central air conditioning and heating system well owing to these characteristics above. Radial impeller cooling/heat meter of ACM **0 series Available to: 1. Network 2. The calculator is suitable for a pinup by departing it form the flow meter Features: 1. Jam-proof design 2. Nonmagnetic design 3. Power supplied by external bus
