The WS type Woltman meter will show its advantages during f uctuating flow rates. Since the turbine is arranged perpendicular to the pipe axis, there is no need for a direction change of the transmission through the worm gear to the counter. WS meters can achieve smaller starting values than WP meters through reduced friction.
The hydrodynamic optimized turbine is reliably operated already at small flow rates and "upwards" it has enough power reserves to reliably measure flow rate peaks. Especially strong bearings with low friction guarantee a long life of the meter.
Retrof tting with active and passive pulsers is possible at any time without damaging the calibration seal. With the Reed sensor, optical and inducti-ve-NAMUR sensors all common sensor variations are possible and make the integration in data communication or automation and control systems very easy.

ZENNER FUZHOU Water Meter Co., Ltd, located in the Jinshan Industrial area in Fuzhou, is the subsidiary company of Minol ZENNER Group Germany. The company registered in August, 1996, and it put into production in August 1998. It's the only one enterprise in China that mainly manufactures Woltman meters. The company has absolute ability of technical development and production. It has been certified by the ISO9001: 2000 quality control system, and many kinds of Woltman meters have passed EEC APPROVAL. Furthermore, the company is responsible for the commercial activities and products (water meters, heat meters and remote meter readout systems) sales of ZENNER Germany in China. Adjusting measures to Chinese conditions, ZENNER FUZHOU has brought in and developed various types of Woltman meters, which are based on German technology and meeting the demands of Chinese market. Besides, the water meters have the quality of world-class in the contemporary era and they are suitable for the Chinese situation. Such as WPH40-65mm (national patent product, patent No: ZL00240645.4), WS(national patent product, patent No: ZL982 27502.1, ZL01273001.7), WPV, WI and warm water meters and hot water meters etc. The tenet of ZENNER FUZHOU is to localize the modernized Woltman meters of high quality and high technology content, providing the vast majority of users with the products that adapt to the situation of China in terms of better performance and price.
