Five different antennas are available for use with the unit depending on the application. There are four horn antennas and one Wave-Stick antenna. The Wave-Stack antenna has several different part numbers which correspond to the different lengths of waveguide that lead to the radiating potion of the Wave- Stick. We tested the 6in Wave-Stick.

The BM 702 level gauge does not form part of an overfill protection system as defined in the WHG (= German water pollution regulation). Local codes and regulations apply to its use in hazardous areas. Responsibility as to suitability and intended use of these level gauges rests solely with the user. Improper installation and operation of our level gauges may lead to loss of warranty. In addition, the "General conditions of sale", form the basis of the purchasing contract. If you need to return the level gauge to the manufacturer or supplier, please refer to the information given in Section 5 i Handling and storage Safety advice Depending on the version, the device will weigh between approx. 5 kg and 30 kg. To carry, use both hands to lift the device carefully by the converter housing. If necessary, use lifting gear. When handling the BM 702, avoid hard blows, jolts, impact, etc. When storing the "Wave-Stick" version, make sure that the device is not placed on its side on the PTFE antenna, as this may cause the rod to bend.

RF Exposure Evaluation A calculation based on the FCC’s Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields (Edition 97-01) appears below. Since conducted power measurements were unable to be made, output power was calculated using radiated field strength readings. Antenna Output = 117.7dBuV/m @ 1m ERP=4πPDR 2 where PD= power density, R= measurement distance [m] PD=(field strength) 2 /( free space impedance) 117.7dBuV/m = 0.767V/m PD=(0.767) 2 / 377 = 0.00156W/m 2 ERP=4π x 0.000118 x 1 2 = 0.0196 = 19.6mW The limit for General Population/Uncontrolled Exposure is S=1mW/cm 2 The distance from the antenna at which this radiation level will be reached is R=SQRT(EIRP/4πS) EIRP = 1.64 x ERP R=SQRT(1.64 x 19.6 / (4π x 1)) = 1.6cm Due to this small distance and general installation practice (installed inside an RF tight metal tank), the danger of harmful RF radiation exposure from this device is minimal.
